We will determine the final speed as follows:

So, superman's final velocity is approximately 201 m/s.

[In this case superman's initial velocity is a datapoint that is not necessary]

The total kinetic energy of the system of the two objects can be achieved by adding of the kinetic energies of first and second body.

Kinetic energy is directly proportional to the mass of the thing and to the square of its velocity: K.E. = 1/2 m v². If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. So the formula for kinetic energy is that it's equal to 1/2 times the mass of the object, times the immensity of its velocity squared, or another way to think about it, its speed squared. In an elastic collision, both the impulse and the kinetic energy of the system are maintained. On the other hand, in an inelastic collision, momentum is sustained but kinetic energy can not be sustained.

So we can conclude that two objects of equal mass moving with equal speeds in opposite directions have a total momentum of zero, but their total kinetic energy is not zero.

With 1 scoop of flour, Olivia can bake 15 biscuits if the the equation that shows the relation between number of biscuits and amount of flour is c = 15f.

c = 15 f

c = Number of biscuits

f = Number of scoops of flour

f = 1

c = 15 * 1

c = 15

This equation shows that number of biscuits that can be made is 15 times the number of scoops of flour. So if the number of scoops of flour is 1, the number of biscuits that can be made is 15.

Monocular depth cues are visual cues that can be perceived with one eye, while binocular depth cues are visual cues that require both eyes to be perceived.

Monocular depth cues include:
- Relative size: Objects that are closer appear larger than objects that are farther away.
- Linear perspective: Parallel lines appear to converge as they get farther away.
- Interposition: Objects that are closer block the view of objects that are farther away.
- Texture gradient: The texture of an object becomes less detailed as the object gets farther away.
- Light and shadow: The way light falls on an object can give the impression of depth.

Binocular depth cues include:
- Retinal disparity: Each eye sees a slightly different image of an object, and the brain uses the difference between these images to judge the distance of the object.
- Convergence: The closer an object is, the more the eyes have to turn inward to focus on it.

Both monocular and binocular depth cues are important for perceiving depth and distance in the world around us.

Answer:

Explanation:

For every action (or force), there is an equal and opposite action (or force).

Answer:

0.05s

Explanation:

frequency = speed / wavelength = 20/1 = 20Hz. Thus period = 1/f = 1/20 = 0.05 s

Frequency = speed / wavelength = 20/1 = 20Hz.

Thus period = 1/f = 1/20 = 0.05 s

Frequency is the number of waves that pass a fixed point in unit time.

The magnetic force vector on the particle is (-350.00 î + 50.00 j) N. Option D) (-350 î + 50.0ỉ) is the correct answer. we can use the equation: F = q * (v x B)

To find the magnetic force on a charged particle moving in a magnetic field, we can use the equation:

F = q * (v x B)

where F is the magnetic force vector, q is the charge of the particle, v is the velocity vector, and B is the magnetic field vector.

Given:

q = -5.00 C (charge of the particle)

v = (1.00 î + 7.00 j) m/s (velocity of the particle)

B = 10.00 T (magnetic field)

Substituting the values into the equation:

F = (-5.00 C) * ((1.00 î + 7.00 j) m/s x (10.00 T) î)

The cross-product of the velocity vector and the magnetic field vector can be calculated as:

v x B = (v_y * B_z - v_z * B_y) î + (-v_x * B_z + v_z * B_x) j + (v_x * B_y - v_y * B_x) k

Substituting the values:

v x B = (7.00 * 10.00) î + (-(1.00 * 10.00)) j + ((1.00 * 7.00) - (7.00 * 1.00)) k

= 70.00 î - 10.00 j + 0.00 k

= 70.00 î - 10.00 j

Now, calculating the magnetic force:

F = (-5.00 C) * (70.00 î - 10.00 j)

= -350.00 î + 50.00 j

Therefore, the magnetic force vector on the particle is (-350.00 î + 50.00 j) N. Option D) (-350 î + 50.0ỉ) is the correct answer.

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.
