Ball A has a mass of 3 kg and is moving with a velocity of 8 m/s when it males a direct collision with ball B, which has a mass of 2 kg and is moving with a velocity of 4 m/s. If e = 0.7, determine the velocity of ball A just after the collision. Neglect the size of the %3D balls. Use absolute value. 8 m/s 4 m/s B
