An elecator in which a man is standing is moving upwards with a speed of `10ms^(-1)` if the man drops a coin from a height of 2.45 m from the floor of elevator it reaches the floor of the elevator after time `(g=9.8ms^(-2))`

An elevator in which a man is standing is moving upwards with a speed of 10m/sec . If the man drops a coin from a height of 2.45 metre, after what time it reaches the floor of the elevator.

In a lift moving up with an acceleration of 5 m s^(-2) , a ball is dropped from a height of 1.25 m. The time taken by the ball to reach the floor of the lift is ……(nearly) ( g = 10 ms^(-2) )

An elevator, in which a man is standing, is moving upward with a constant acceleration of 2 m//s^2 . At some instant when speed of elevator is 10 m//s , the man drops a coin from a height of 1.5 m . Find the time taken by the coin to reach the floor.

An elevator without a ceiling is ascending up with an acceleration of 5 ms^-2. A boy on the elevator shoots a ball in vertical upward direction from a height of 2 m above the floor of elevator. At this instant the elevator is moving up with a velocity of 10 ms^-1 and floor of the elevator is at a height of 50 m from the ground. The initial speed of the ball is 15 ms^-1 with respect to the elevator. Consider the duration for which the ball strikes the floor of elevator in answering following questions. ( g=10 ms^-2 ) 1. The time in which the ball strikes the floor of elevator is given by
