Question:

Figure 6.11 shows two identical balls A and B about to make a head-on collision. After the collision, ball A rebounds at a speed of 1.5 m s⁻¹ and ball B rebounds at a speed of 2.5 m s⁻¹. The mass of each ball is 4.0 kg.

a. Calculate the momentum of each ball before the collision.

b. Calculate the momentum of each ball after the collision.

c. Is the momentum conserved in the collision?

d. Show that the total kinetic energy of the two balls is conserved in the collision.

e. Show that the relative speed of the balls is the same before and after the collision.
