A ball falls from a height of 5m and strikes a lift which is moving in the upward direction with a velocity of 1m/s, then the velocity with which the ball rebounds after collision will be -
Text Solution
Verified by ExpertsThe correct answer is:
B
Velocity after a fall of 5m = 
= 10 m/s
= e ( 
)
= 1 – (–10) = 12 m/s
