A football player throws a football 30 meters in 2.5 seconds, divide 30 by 2.5 and get 12.

An object's speed, also known as "v," is the amount by which its position changes over time or by how much it changes per unit of time, making it a scalar number.  

The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance traveled by the object divided by the duration of the period. Velocity and speed are not the same thing.

The parameters of speed are time divided by distance. The metre per second (m/s), the SI measure of speed, is the most widely used unit of speed in daily life.

Therefore, A football player throws a football 30 meters in 2.5 seconds, divide 30 by 2.5 and get 12.

Answer: total mass number

Explanation:

Answer:

By Gauss' Law the sphere will appear externally as if all of the charge were concentrated at the center of the sphere.

E = K Q / r^2 = K Q / .528^2

Q = 1710 * .528^2 / 9.00E9 Coulombs

Q = 5.30E-8 Coulombs on sphere

V = 4/3 π R^3 = 4/3 π * .384^3 = .237 m^3

ρ = Q / V = 5.30E-8 / .237 = 2.23E-7 C/m^3

At .223 from center Q = 4/3 π .223^3 * ρ  (charge outside this radius will not affect electric field outside .223 m)

Q = 2.23E-7 * 4/3 * π * .223^3 = 1.04E-8 Coulombs

E = 9.00E9 * 1.04E-8 / .223^2 = 1880 N/C

The mass of a hockey puck, m = 0.21 kg

The kinetic energy of the hockey puck, E= 74 J

We need to find the speed of the hockey puck. Let the speed is v. We know that, the kinetic energy is given by :

\(E=\dfrac{1}{2}mv^2\)

Where

v is the speed

So,

\(v=\sqrt{\dfrac{2E}{m}} \\\\v=\sqrt{\dfrac{2\times 74}{0.21}} \\\\v=26.54\ m/s\)

So, the speed of the hockey puck is 26.54 m/s.

The Earth does 40 Joules of Work on the book as it drops 2 meters.

Because, when an object is dropped, gravity pulls it down towards the center of the Earth. In this case, the Earth exerts an upward force of 20 Newtons on the book to counteract the force of gravity.

The work done by the Earth on the book can be calculated as follows:

\(Work = Force x Distance x Cosine(theta)\)

In this case, the force is 20 Newtons, and the angle between the force and the distance is 0 degrees (since the force is acting in the same direction as the distance).

So,

\(Work = 20 N x 2 m x Cos(0) = 40 Joules\)

Therefore, the Earth does 40 Joules of work on the book as it drops 2 meters.

Answer:

Claim: The cotton ignites in the piston due to the transfer of thermal energy from the compressed air.

Evidence: When the piston is rapidly pushed into the cylinder, it compresses the air inside, causing the air molecules to collide and generate heat. This increase in temperature is then transferred to the small piece of cotton located at the bottom of the piston, causing it to ignite and produce a flame.

Reasoning: The transfer of thermal energy from the compressed air to the cotton occurs due to the process of conduction. The compressed air directly contacts the cotton, transferring its heat energy to the cotton through direct contact. As the temperature of the cotton increases, it reaches its ignition point and starts to burn. Therefore, the cotton ignites due to the transfer of thermal energy from the compressed air through conduction.

The net work required to cause the particle to move to the right at 47 m/s is 30.102 Joules.

To determine the net work required to change the particle's velocity from moving left at 27 m/s to moving right at 47 m/s, we can use the work-energy principle.

The work-energy principle states that the net work done on an object is equal to the change in its kinetic energy.

The kinetic energy of a particle is given by the equation:

KE = (1/2) * m * v^2

where m is the mass of the particle and v is its velocity.

Let's calculate the initial kinetic energy (KE_initial) and final kinetic energy (KE_final) of the particle.

Given:

Mass of the particle (m) = 41 g = 0.041 kg

Initial velocity (v_initial) = -27 m/s (negative sign indicates motion to the left)

Final velocity (v_final) = 47 m/s

Calculate the initial kinetic energy:

KE_initial = (1/2) * m * v_initial^2

= (1/2) * 0.041 * (-27)^2

= 0.5 * 0.041 * 729

= 14.9575 J

Calculate the final kinetic energy:

KE_final = (1/2) * m * v_final^2

= (1/2) * 0.041 * 47^2

= 0.5 * 0.041 * 2209

= 45.0595 J

Calculate the net work done:

Net work = KE_final - KE_initial

= 45.0595 - 14.9575

= 30.102 J

Therefore, the net work required to cause the particle to move to the right at 47 m/s is 30.102 Joules.

Answer:

The effective spring constant of the firing mechanism is approximately 21.804 N/m

Explanation:

The mass of the circus performer, m = 75.6 kg

The angle of elevation above the horizontal, θ = 37.2°

The instrument the cannon uses to propel the performer = Strong elastic band

The length by which the band stretches, x = 2.70 m

The height of the performer above the floor at the point the performer flies free of the bands = The height of the net into which he is shot

The time he takes to travel the horizontal distance between the point he is shot and the net, t = 2.34 s

The horizontal distance between the the point he is shot and the net, dₓ = 26.9 m

Therefore, the horizontal component of the velocity, vₓ, can be found with the following kinematic equation of motion;

vₓ = dₓ/t

∴ vₓ = 2.70 m/(2.34 s) = (15/13) m/s

By the resolution of the initial velocity, 'v', into the horizontal and vertical component, we have;

The horizontal component, vₓ = v × cos(θ)

∴ v = vₓ/(cos(θ))

v = (15/13)/(cos(37.2°)) ≈ 1.45

The initial velocity, v ≈ 1.45 m/s

The kinetic energy given to the circus performer by the elastic band, K.E., is given as follows;

K.E. = (1/2)·m·v²

Where;

m = The mass of the performer = 75.6 kg

v = The velocity given to the performer ≈ 1.45 m/s

∴ K.E. ≈ (1/2) × 75.6 × 1.45² ≈ 79.475

∴ K.E. ≈ 79.475 J

The kinetic energy, K.E., given to the performer, (1/2)×m×v² = The kinetic energy of the elastic band = (1/2)×k×x²

Where;

k = The effective spring constant of the firing mechanism

x = The extension of the sling = 2.70 m

Therefore, we get;

K.E. = (1/2)·m·v² = (1/2)·k·x²

∴ K.E. ≈ 79.475 J = (1/2) × 75.6 × 1.45² = (1/2) × k × (2.70 m)²

∴ 79.475 J ≈ (1/2) × k × (2.70 m)²

k = 79.475 J/((1/2) × (2.70 m)²) ≈ 21.804 N/m

The effective spring constant of the firing mechanism, k ≈ 21.804 N/m.

Explanation:

A fuel-filled rocket is at rest. It burns its fuel and expels hot gas. The gas has a momentum of 1,500 kg m/s backward. So, The momentum of the rocket is -1500 kg m/s.

According to the law of conservation of momentum, in a closed system, the total momentum before and after a process remains constant.

A fuel-filled rocket that is initially at rest expels hot gas as it burns its fuel. The gas has a momentum of 1500 kg m/s backward.

We are required to determine the momentum of the rocket.

Consider the fuel-filled rocket as a system.

We have: Momentum before the burn = 0 kg m/s (since the rocket was at rest initially)Momentum after the burn = momentum of the expelled gas

We can therefore say that the initial momentum of the system was zero (0), and after the burn, the total momentum of the system remains the same as the momentum of the expelled gas.

Therefore: Momentum of rocket = - momentum of expelled gas

The negative sign signifies that the rocket's momentum is in the opposite direction of the expelled gas.

Hence, the momentum of the rocket is -1500 kg m/s.

When standing on a train accelerating at 0.30 g, there is an effective force acting on you due to the acceleration. This force is equivalent to the force that would be experienced by an object with mass m = your mass under the influence of gravity and this force is resisted by the static friction force:

F = m * a

where a is the acceleration of the train and g is the acceleration due to gravity (approx. 9.81 m/s^2).

To avoid sliding on the floor of the train, the static friction force between your feet and the floor must be greater than or equal to the force due to the acceleration of the train. Therefore, we have:

f_s >= m * a

where f_s is the static friction force.

The maximum static friction force that can act between your feet and the floor is given by:

f_s = μ_s * N

where μ_s is the coefficient of static friction between your feet and the floor, and N is the normal force acting on your feet.

Since you are standing still relative to the train, the normal force acting on your feet is equal to your weight, which we can express as:

N = m * g

Substituting this into the expression for the maximum static friction force, we get:

f_s = μ_s * m * g

Substituting this expression for f_s into the inequality above, we get:

μ_s * m * g >= m * a

Simplifying this expression, we get:

μ_s >= a / g

Substituting a = 0.30 g and g = 9.81 m/s^2, we get:

μ_s >= 0.30

Therefore, the minimum coefficient of static friction that must exist between your feet and the floor to avoid sliding on the train is 0.30.

Therefore, the electric field (magnitude only) at a distance of 8.0 cm from the wire is approximately 3.24 x 10^4 N/C.

The electric field of a long, thin wire can be determined by Coulomb's law. Coulomb's Law states that the electric force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

For a long, thin wire, the electric field is given by;

E = λ/2πε₀r

Where;

λ = linear charge density = 91 µC/m,

ε₀ = permittivity of free space = 8.85 x 10^-12 C^2/Nm^2

r = distance from the wire = 8.0 cm = 0.08 m.

Substitute the given values into the formula to find the electric field;

E = (91 x 10^-6)/(2 x π x 8.85 x 10^-12 x 0.08)

E≈ 32433.8 N/C

E≈ 3.24 x 10^4 N/C.
