Ball A has a mass of 3 kg and is moving with a velocity
of (VA)1 = 8 m/s when it makes a direct collision with
ball B, which has a mass of 2.5 kg and is moving with a
velocity of (VB) 1 = 4 m/s. Suppose that e = 0.7.
Neglect the size of the balls. (Figure 1)
Part A
Determine the velocity of A just after the collision.
