Explanation:
Two balls of masses 2 kg and 4 kg are moved towards each other with velocities 4m/s and 2m/s, respectively, on a frictionless surface. After colliding, the 2 kg ball returns back with velocity 2m/s. Then find
(a) velocity of the 4 kg ball after collision
(b) coefficient of deformation e
c) impulse of deformation J
(d) Maximum potential energy of deformation
(e) impulse of reformation
