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–1.
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–1. 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-1 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 ?
