Which one of the following free-body diagrams best represents the free-body diagram, with correct relative force magnitudes, of a person in an elevator that is traveling upward with an unchanging velocity? _f is the force of the floor on the person and
_g is the force of gravity on the person.

Question

Which one of the following free-body diagrams best represents the free-body diagram, with correct relative force magnitudes, of a person in an elevator that is traveling upward with an unchanging velocity?

_f is the force of the floor on the person and Which one of the following free-body diagrams best represents the free-body diagram, with correct relative force magnitudes, of a person in an elevator that is traveling upward with an unchanging velocity? <sub>f</sub> is the force of the floor on the person and <sub>g</sub> is the force of gravity on the person. A) B) C) D) E)

_g is the force of gravity on the person.

Quizplus · Accepted Answer

Since the elevator is traveling upward with a constant velocity, the net force on the person must be zero. This means that the upward force from the floor (_f) must be equal in magnitude to the downward force of gravity (_g). Therefore, the free-body diagram should show those two forces as equal in magnitude and opposite in direction. Choice B is the only diagram that accurately represents this situation.
