Momentum and CollisionEasy
Question
A ball falls from a height of 5m and strikes the roof of a lift. If at the time of collision, lift is moving in the upward direction with a velocity of 1m/s, then the velocity with which the ball rebounds after collision will be - (e = 1)
Options
A.11 m/s downwards
B.12 m/s upwards
C.13 m/s upwards
D.12 m/s downwards
