JEE Main Physics question
A very broad elevator is going up vertically with a constant acceleration of 2 ms. At the instant when its velocity is 4 ms, a ball is projected from the floor of the lift with a speed of 4 ms relative to the floor, at an elevation of . The time taken by the ball to return to the floor is ( ms)
Answer: (B)
Solution
In the (accelerating) lift frame, the effective downward gravity is ms. The vertical component
