A lift is moving with uniform downward acceleration of 2 `m//s^(2)` . A ball is dropped from a height 2 metre from the floor of lift. Find the time after which ball will strike the floor.

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) )

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) )

If a ball is dropped from height 2 metre on a smooth eleastic floor, then the time period of oscillation is

A block of mass 2kg is kept inside a lift. Lift starts moving downward with an acceleration of a=12m/ s^(2) .Height of the lift is 4m .Time after which block will strike roof of the lift is?

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.

At an instant lift is moving with "10m/s" upward "and with acceleration 5m/s^(2) upward.At the same instant,a coin is dropped from "7.5m" above the floor of lift,find the distance travelled by coin in ground frame before it strikes the floor:-

An open lift is moving upward with velocity 10 m//s. It has an upward acceleration of 2 m//s^2. A ball is projected upwards with velocity 20 m//s relative to ground. Find (a) time when ball again meets the lift (b) displacement of lift and ball at that instant. (c) distance travelled by the ball upto that instant. Take g=10 m//s^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 lift is going up with an acceleration 2 g. A man is inside the lift and his mass is m What will be the reaction of the floor on the man ?
