A student is standing in an elevator that travels from the first floor to the thenth floor of a building. The student exerts the greatest force on the floor of the elevator when the elevator is

accelerating upward as it leaves the first floor.

Explanation:

When a person moves up in the elevator, the person's apparent weight is less then the actual weight. The person feels less weight than his or her actual weight. But just before the elevator starts moving the apparent weight of the person is equal to the normal or actual weight of the person before the movement. And after moving up in the elevator, the apparent weight is less than the actual weight, as one is moving against the force of gravity.

So in the context, the student exerts greatest force on the 1st floor as the elevator is accelerating upward when it leaves the first floor.
