An object's impulse is the change in its momentum. The ball's impulse has a mass of m, an initial velocity of u, and a final velocity of u. (Uf - Ui).

Describe impulse.

An objective measurement of a moving object's change in momentum is called impulse. An object's momentum is calculated by multiplying its mass and speed.

Thus, momentum equals m v.

Let L1 represent the ball's starting momentum.

mass = m

initial speed = Ui

L1 = m Ui.

Let L2 represent the final momentum and Uf represent the final speed.

L2 = m Uf.

Impulse = L1 - L2

m Ui - m Uf

= m (Uf - Ui) (Uf - Ui)

Consequently, the ball's impulse is m. (Uf - Ui).

152.8 kg.m/s is the momentum of the combined masses. 15.28 m/s is the velocity of the combined masses.

To find the momentum of the combined masses after the collision, we can use the principle of conservation of momentum. This states that the total momentum of a closed system is conserved, meaning that the total momentum before the collision is equal to the total momentum after the collision. In this case, the total momentum before the collision is the momentum of the 4.00 kg ball plus the momentum of the 6.0 kg ball. The total momentum after the collision is the momentum of the combined masses.

We can express the principle of conservation of momentum as an equation: p_before = p_after

(m1 * v1) + (m2 * v2) = (m1 + m2) * vafter

where p stands for momentum, m for mass, and v for speed. The subscripts 1 and 2 refer to the two balls, and the subscript "before" refers to the momentum before the collision and "after" refers to the momentum after the collision.

Substituting in the known values, we get:

(4.00 kg * 11.2 kg.m/s) + (6.0 kg * 18 kg.m/s) = (4.00 kg + 6.0 kg) * v_after

44.8 kg.m/s + 108 kg.m/s = 10.00 kg * v_after

152.8 kg.m/s = 10.00 kg * v_after

v_after = 15.28 m/s

So the momentum of the combined masses after the collision is 152.8 kg.m/s and the velocity of the combined masses is 15.28 m/s.

The distance of 9.54cm, the concave mirror from his face.

What is a Concave mirror?

The reflective surface of a concave mirror is sloped inward and away from the light source. Light is reflected inward to a single focal point via concave mirrors. Contrary to convex mirrors, concave mirrors provide a variety of images based on the object's distance from the mirror.

What is Distance?

Regardless of the direction of the path, distance is the overall path that an object in motion has travelled. Since only the length of the path travelled is calculated and the direction of motion is not considered, distance is referred to as a scalar quantity. The distance can only be positive; it can never be zero or negative.

Calculations:

focal length is f = R/2 (R = Radius of curvature = 31.8cm)

f = 31.8/2

f = 15.9 cm

an upright image 2.51 times the object size corresponds to the magnification of m = -i/p

i = -2.51p

use mirror equation = 1/f = 1/p + 1/i = 1/p - 1/2.51p = 0.6/p
