A very broad elevator is going up vertically with a constant acceleration of `2m//s^(2)`. At the instant when its velocity is `4m//s`, a ball is projected from the floor of the lift wht as of `4m//s` relative to the floor at an elevation of `30^(@)`. The time taken by the ball to return the floor is `(g=10m//s^(2))`

A very broad elevator is going up vertically with constant acceleration of 2 m/s^(2) . At the instant when its velocity is 4 m/s a ball is projected from the floor of the lift with a speed of 4 m/s relative to the floor at an elevation of 30^(@) . The range of ball over the floor of the lift is :

An elecator is going up with an upward acceleration of 1m//s^2 . At the instant when its velocity is 2 m//s , a stone is projected upward from its floor with a speed of 2m//s relative to the elevator, at an elevation of 30^@ . (a) Calculate the time taken by the stone to return to the floor. (b) Sketch the path of the projectile as observed by an observer outside the elevator. (c) If the elevator was moving with a downward acceleration equal to g, how would the motion be altered?

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.
