If the magnitude of the average rate at which the gravity force does work on the student equals 500 WW, how long would it take the student to travel up the three flights of stairs

answer: its c lololo

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

pretty sure it's false
