1. The problem statement, all variables and given/known data A person weighing 0.6 kN rides in an elevator that has a downward acceleration of 3 m/s2. The acceleration of gravity is 9.8 m/s2 . What is the magnitude of the force of the elevator floor on the person? Answer in units of kN. 2. Relevant equations F = ma 3. The attempt at a solution Is the downward acceleration of the elevator and gravity in the same direction, so should the acceleration in the formula equal the sum of the acceleration of the elevator and gravity. Or are they in opposite directions?
