Question

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to 49 m/s. How much time does the ball take to return to his hands? If the lift starts moving up with a uniform speed of 5 m/s and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands?​

Hello swarish hru good morning, hope it will help you✨

In the case where the lift also moves, the relative velocity of the ball with respect to the boy remains the same, i.e, 49 ms-1. The relative displacement is also 0. Hence the time required in this case is also 10 s.
