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.
