A coin is dropped in a lift. It takes time t_(1) to reach the floor when lift is stationary. It takes time t_(2) when lift is moving up with costant acceleration. Then

A body is thrown up with a velocity 100ms^(-1) it travels 5 m in the last swecond of upward journey if the same body thrown up with velocity 200ms^(-1) , how much distance (in metre) will it travel in the last second of its upward journey (g=10ms^(-2))

A particle is thrown up inside a stationary lift of sufficient height. The time of flight is T. Now it is thrown again with same initial speed v_0 with respect to lift. At the time of second throw, lift is moving up with speed v_0 and uniform acceleration g upward (the acceleration due to gravity). The new time of flight is:
