Problem 7: The floor to ceiling height of an elevator is 4.5 m. The elevator starts from the ground at rest and accelerates upward at 6 m/s2. At t=1 s, a lamp on the elevator ceiling starts to fall (due to high g forces). How long will it take the lamp to hit the floor? Solve this problem in two ways: a) From the perspective of a fixed X-Y frame (the ground frame). b) From the perspective of a frame moving with the elevator (the relative frame). In both cases, clearly show (in a schematic diagram) the origin and the axes of the frames you choose.
