## Homework Statement

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.

## Homework Equations

F = ma

## 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?
