Two balls A and B having masses 1 kg and 2 kg, moving with speeds 21 m/s and 4 m/s respectively in opposite direction, collide head on. After collision A moves with a speed of 1 m/s in the same direction, then correct statements is :
- (A):The velocity of B after collision is 6 m/s opposite to its direction of motion before collision.
- (B):The coefficient of restitution is 0.2.
- (C):The loss of kinetic energy due to collision is 200 J.
- (D):The impulse of the force between the two balls is 40 Ns.
