A person in a lift which ascends up with acceleration 10m/s2 drops a stone from a height 10m. Time of descent is A) 1 sec B) 2 sec C) 1.5 sec D) 3 sec

Starting from rest, A lift moves up with an acceleration of 2 ms^(-2) . In this lift , a ball is dropped from a height of 1.5m (with respect to floor of lift). The time taken by the ball to reach the floor of the lift is ( g=10 ms^(-2) )

A lift whose cage is 3 m high is moving up with an acceleration of 2m//s^(2) . A piece of stone is dropped from the top of the cage of the lift when its velocity is 8m/s. if g=10m//s^(2) , then the stone will reach the floor of the lift after

A stone is relaeased from an elevator gaing up with acceleration 5m//s^(2). The acceleration of the stone after the release is :

A balloon starts rising from ground from rest with an upward acceleration 2m//s^(2) . Just after 1 s, a stone is dropped from it. The time taken by stone to strike the ground is nearly

A lift is moving with a uniform downward acceleration of 2 m//s^(2) . A ball is dropped from a height 2 m from the floor of lift. Find the time taken after which ball will strke the floor ? (Take g = 10 m//s^(2) )

A balloon a ascending vertically with an acceleration of 0.4m//s^(2) . Two stones are dropped from it at an interval of 2 sec. Find the distance between them 1.5sec. after the second stone is released. (g=10m//sec^(2)) .

A particle is thrown upwards from ground it experiences a constant resistance force which can produce retardation of 2m/s^2 The ratio of time of ascent to the time to descent is (g=10m/s^ 2)
