The upward normal force exerted by the floor is 620 N on an elevator passenger who weighs 650 N.

What is the magnitude of the acceleration?

What is the direction of the acceleration? (upward or downward)

♦ Relevant knowledge
Acceleration is the speed of change in an object’s speed. Velocity refers to the speed at which an object moves in a certain direction. Therefore, acceleration is the measure of the speed at which velocity alters. Acceleration can be calculated when we know the complete change in velocity and the amount of time it takes for the speed to change.

The units used for acceleration are m/s^2, however there is a different measurement that is needed. Acceleration, as with velocity is a vector value. That means that you will need to determine your direction too. Additionally, acceleration could be either positive or negative.
