A woman stands in an elevator that has a constant upwardacceleration while the elevator travels upward a distance of18.0 m. During the 18.0-m displacement,the normal force exerted by the elevator floor does 8.25kJ of work on her and gravity does -7.35 kJ of work on her.

A) What is the mass of the woman?

B) What is the normal force that the elevator floor exerts onher?

C) What is the acceleration of the elevator?
