Astudent whose normal weight is 500 newtons stands on a scale in a elevator. displacement, velocity, and acceleration are upward. what is the acceleration for each 5 second interval.

0-5 seconds and 10-15 seconds: zero acceleration, constant velocity (may be zero)

5-10 seconds: upward acceleration, velocity increasing upwards or decreasing downwards

15-20 seconds: downward acceleration, velocity decreasing upward or increasing downward

explanation:

newton's third law, for every action there is an equal and opposite reaction.
