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 is accelerating upwards with a constant acceleration a ms^-2 . If a coin is dropped in it by a passenger, then.

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.

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 car (lift) is moving upward with uniform acceleration of 2 m//s^(2) . At the instant, when its velocity is 2 m/s upwards a ball thrown upward from its floor. The ball strikes back the floor 2s after its projection. Find the velocity of projection of the ball relative to the lift.

An elevator car (lift) is moving upward with uniform acceleration of 2 m//s^(2) . At the instant, when its velocity is 2 m/s upwards a ball thrown upward from its floor. The ball strikes back the floor 2s after its projection. Find the velocity of projection of the ball relative to the lift.

A girl is standing in an elevator that is moving upward at a velocity of 5m//s and acceleration 2 m//s^(2) , when she drops her handbag. If she was originally holding the bag at a height of 1.5 m above the elevator floor, how long will it take the bag to hit the floor
