Q: A block A of mass 0.5 kg can slide on a frictionless incline of angle 30o and length 0.8 m kept inside an elevator going up with uniform velocity 2m/s. Find the time taken by the block to slide down the length of the incline if it is released from the top of the incline. Take g = 10 ms-2.

1. If the elevator is not accelerating it is not part of the problem.
I bet you can do it ignoring the elevator.
By the way the mass of the block is also irrelevant because it cancels (remember feathers and rocks fall together in a vacuum)
