When the elevator is mobing upwards but its slowing to a stop at the top floor. what is the direction of the net firce on the rider?

Explanation:

If an elevator is moving upwards but slowing down to stop at top floor then it implies that elevator is decelerating i.e. a net force is acting downward which opposes the motion .

N-mg=m(-a)

-a indicates that elevator is decelerating

where N=Normal reaction

mg=weight of rider

a=acceleration of elevator

so easy. just google the electromagnetic waves and it’ll pop up.
