A man hits a 50g golf ball such that it leaves the tee at an angle of 40 degrees with the horizontal and strikes the ground at the same elevation a distance of 20 m away. Determine the impulse of the golf club on the ball. Neglect the impulse caused by the ball's weight while the club is striking the ball.
Answers
To determine the impulse of the golf club on the ball, we will follow these steps:
Step 1: Calculate the initial velocity of the golf ball
We know the horizontal distance (20 m) and the angle (40 degrees) of the golf ball's trajectory. We can use the horizontal range formula:
\(Range = \frac{ (v^2 * sin(2 * angle))}{g} \\20m = \frac{ (v^2 * sin(2 * 80))}{9.18} \\\\v^2 = \frac{20 * 9.18}{sin(80)} \\v = 20.34 ms^-^1\)
Step 2: Determine the change in velocity during the impact
Since the ball comes to a stop after being hit, the change in velocity (Δv) is equal to the initial velocity:
Δv = 20.34 m/s
Step 3: Calculate the impulse using the impulse-momentum theorem
The impulse-momentum theorem states:
Impulse = mass * Δv
The mass of the golf ball is 50 g, which is 0.05 kg. Using this, we can calculate the impulse:
Impulse = 0.05 kg * 20.34 m/s
Impulse ≈ 1.017 kg·m/s
So, the impulse of the golf club on the ball is approximately 1.017 kg·m/s.

A crate with a mass of 100 kg sits on a flat horizontal surface. If a person slides the crate with a constant velocity across the floor with a force of 325 N, what is the coefficient of kinetic friction between the crate and the floor?
Please show work :)
Answers
The create is moving at a constant velocity, so there is no acceleration and the crate is in equilibrium. This means the net force acting on the crate is 0. By Newton's second law, we have
n - w = 0
s - f = 0
where n denotes the magnitude of the normal force acting on the crate, w denotes its weight, s is the magnitude of the force applied by the person (s for sliding), and f is the magnitude of the kinetic friction force.
The friction force is proportional ot the normal force by a factor of µ, the coefficient of kinetic friction. So we have
n = w = (100 kg) (9.80 m/s²) = 980 N
s = f = µ n → 325 N = µ (980 N) → µ = (325 N) / (980 N)
So the coeficient of kinetic friction is approximately µ ≈ 0.332.
A 0.5 kg soccer ball is kicked with a force of 60 N for 0.3 seconds. The ball was originally at rest.
What is the velocity of the ball after the kick?
Answers
Answer:
To determine the velocity of a soccer ball after a kick, it is crucial to use the equation:
force = mass x acceleration
It is possible to rearrange this equation to solve for acceleration:
acceleration = force / mass
Knowing that the force applied to the ball is 60 N and the mass of the ball is 0.5 kg, we can find the acceleration of the soccer ball, which is:
acceleration = 60 N / 0.5 kg = 120 m/s^2
The next step is to use the equation:
velocity = acceleration x time
The duration of the kick, which is 0.3 seconds, is represented by time in the equation.
Therefore, the velocity of the soccer ball after the kick can be calculated as follows:
velocity = 120 m/s^2 x 0.3 s = 36 m/s
Hence, the critical terms in this calculation are force, mass, acceleration, velocity, and time. It is essential to use these terms accurately and calculate them correctly to determine the velocity of a soccer ball after a kick.

Answers
(1) The moment of 20N about the wheel is 30 Nm. (2) The distance of the wheel to the center of mass of the wheelbarrow is 1.2m.
1. The moment of 20N about the wheel can be calculated using the formula:
Moment = Force x Distance
Moment = 20N x 1.5m
Moment = 30 Nm
2. To find the distance of the wheel to the center of mass of the wheelbarrow, we can use the principle of moments, which states that the sum of the clockwise moments about a point is equal to the sum of the anticlockwise moments about the same point. Let the distance from the wheel to the center of mass be x.
Clockwise moment = Weight x Distance
Clockwise moment = 80N x (1.5m - x)
Anticlockwise moment = Upforce x Distance
Anticlockwise moment = 20N x x
Using the principle of moments:
80N x (1.5m - x) = 20N x x
Simplifying and solving for x:
120m = 100x
x = 1.2m
Therefore, the distance of the wheel to the center of mass of the wheelbarrow is 1.2m.

Answers
A sound wave has a speed of 342 m/s and a wavelength of 2.15 meters. 159 hertz is the frequency of this wave. Option A is Correct.
When a wave undergoes reflection, it essentially remains in the medium and only changes directions. The gentle wave has travelled twice as far. Sound waves may be accurately used to locate this reflection characteristic of waves.
You may continually hear the echo of the yell when you let out a wild scream within a chasm. In this case, the air and vibrations off the gorge wall act as the medium through which the sound waves travel before returning to their source (you). The result is that you hear your shout reverberate.
The formula to calculate frequency is:
frequency = speed of sound / wavelength
Plugging in the values given:
frequency = 342 m/s / 2.15 m
frequency = 159 hertz

which takes more work, accelerating a car from 10 to 20 m/s or from 20 to 30 m/s? explain why.
Answers
The work required is greater for accelerating the car from 20 to 30 m/s than from 10 to 20 m/s.
The effort is greater when the car is accelerated from 20 to 30 m/s than from 10 to 20 m/s due to the change in kinetic energy. This is due to the fact that an object's kinetic energy grows as a function of velocity, hence as velocity rises, so does the amount of work needed to produce a given increase in kinetic energy.
The kinetic energy of an object determines how much labour is necessary to accelerate it from one velocity to another.
The equation: gives the kinetic energy of an item
K = (1/2)mv^2
where
m is the mass of the object
v is its velocity.
We have to find the at which velocity a car required more work to accelerate a car from 10 to 20 m/s or from 20 to 30 m/s we can find it by comparison,
To determine the change in kinetic energy, we may compute the car's kinetic energy at each velocity and then subtract the beginning kinetic energy from the final kinetic energy.
Let's take mass of that the car is 1000 kg.
Case1: accelerating the car from 10 m/s to 20 m/s:
Initial kinetic energy \(= (1/2)mv^2\)
Initial kinetic energy \(= (1/2)(1000 kg)(10 m/s)^2\)
Initial kinetic energy \(= 50,000 J\)
Final kinetic energy \(= (1/2)mv^2\)
Final kinetic energy \(= (1/2)(1000 kg)(20 m/s)^2\)
Final kinetic energy \(= 200,000 J\)
Change in kinetic energy = 200,000 - 50,000
Change in kinetic energy = 150,000 J
Case2: accelerating the car from 20 m/s to 30 m/s:
Initial kinetic energy \(= (1/2)mv^2\)
Initial kinetic energy \(= (1/2)(1000 kg)(20 m/s)^2\)
Initial kinetic energy \(= 200,000 J\)
Final kinetic energy \(= (1/2)mv^2\)
Final kinetic energy \(= (1/2)(1000 kg)(30 m/s)^2\)
Final kinetic energy \(= 450,000 J\)
Change in kinetic energy = 450,000 - 200,000
Change in kinetic energy = 250,000 J
We can see that accelerating the automobile from 10 to 20 m/s results in less effort than accelerating it from 20 to 30 m/s due to the change in kinetic energy.
The automobile must thus put in more effort to accelerate from a greater velocity than from a lower one.

The new angle of deflection of the north pole of the compass needle compare to its initial deflection is smaller.
The new angle of deflection north pole becomes smaller
The angle of deflection is the angle formed when an object changes course from its original course of direction or target.
The angle of deflection of a particular particle is directly proportional to its charge to mass ratio as it passed through an electric field.
As the wire is continuously being lowered farther from the compass, the angle of deflection of the north pole continues to become smaller when compared to its initial deflection.
Therefore, the new angle of deflection of the north pole of the compass needle compare to its initial deflection is smaller.

What will the expected fixed manufacturing costs be if 18,000 units are produced and sold?
Answers
To calculate the expected fixed manufacturing costs, we need to know the fixed manufacturing costs per unit produced.
The formula for calculating the fixed manufacturing cost per unit is the Fixed manufacturing cost per unit = Total fixed manufacturing cost / Total units produced. So if we have this information, we can use the above formula to calculate the fixed manufacturing cost per unit, and then multiply it by the number of units produced and sold to get the expected fixed manufacturing costs. Let's assume we have the following information: Total fixed manufacturing cost = $60,000Total units produced = 12,000Using the formula above, we can calculate the fixed manufacturing cost per unit: Fixed manufacturing cost per unit = $60,000 / 12,000 units= $5 per unit. To find the expected fixed manufacturing costs if 18,000 units are produced and sold, we can simply multiply the fixed manufacturing cost per unit by 18,000:Expected fixed manufacturing costs = Fixed manufacturing cost per unit x Total units produced and soldExpected fixed manufacturing costs = $5 per unit x 18,000 units. Expected fixed manufacturing costs = $90,000Therefore, the expected fixed manufacturing costs will be $90,000 if 18,000 units are produced and sold.

What role of average kinetic energy of the particles?Temperature is a gauge for the typical kinetic energy of a substance's constituent particles. It is a particle's typical kinetic energy.
A gas's temperature directly relates to the average kinetic energy of its particles. The particles must travel more quickly as the gas warms since their mass is constant.

Answers
Tom must accelerate at a constant rate of 0.25 m/s2 in order to finish the race in a dead heat with Joe.
What is accelerate?Accelerate is an action or process of speeding up or increasing in rate or amount. It is commonly used to describe an increase in the rate of change of velocity, or the rate of change of a variable such as time, speed, or distance. Acceleration can be generated by a variety of forces and factors, such as gravity, electrical current, centrifugal force, friction, and aerodynamic drag.
Tom must have a constant acceleration of 0.25 m/s2 in order to finish the race in a dead heat with Joe. This can be calculated using the equation for average velocity, vavg = (v1 + v2)/2, where v1 is Joe's velocity and v2 is Tom's velocity. If Joe and Tom both have the same final velocity, then their average velocity must be equal.
50 m / 10 m/s + 51 m / (9.75 m/s + a) = (10 m/s + a)

En donde:
Kf es la energía cinética final =0
Ki es la energía cinética inicial
m: es la masa = 2 kg
v: es la velocidad = 5 m/s
Además el trabajo es el producto de la fuerza de rozamiento (Fr) por el desplazamiento (d), por lo que tenemos:
\( -Fr*d = -\frac{1}{2}m*v^{2} \)
\((\mu mg)d = \frac{1}{2}m*v^{2}\)
\( \mu = \frac{v^{2}}{2gd} = \frac{(5 m/s)^{2}}{2*9,81 m/s^{2}*2 m} = 0,64 \)
Por lo tanto, el coeficiente de fricción entre el bloque y el piso es 0,64.

a 10-h inductor carries a current of 20 a. describe how a 50-v emf can be induced across it.
Answers
To induce a 50 V EMF across a 10 H inductor carrying a current of 20 A, the current needs to be rapidly decreased to zero.
When the current in an inductor is changing, an EMF is induced across the inductor according to Faraday's law of electromagnetic induction. This EMF opposes the change in current and is known as the back EMF. In this case, to induce a 50 V EMF across the inductor, the current needs to be rapidly decreased to zero.
This can be achieved by opening the circuit or by using a switch to disconnect the inductor from the power source. When the circuit is opened or the switch is opened, the current in the inductor will rapidly decrease to zero, inducing the back EMF across the inductor. The magnitude of the back EMF is proportional to the rate of change of the current and the inductance of the inductor, so the larger the inductance, the larger the induced EMF.
