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 with a speed of 4m/s, relative to the floor at an elevation of 30^o. The time taken by the ball to return the floor is (g = 10m/s^2 )
