A 32.0 kg girl is in an elevator

accelerating downward at

-0.850 mls. How much normal

force is acting on her?

(Unit = N)

The normal force acting on the girl is 286.4 N

Explanation:

Given;

mass of the girl = 32.0 kg

a = -0.85 m/s²

The normal force or normal reaction (R) on the girl, includes force of gravity and downward force on her due to her downward acceleration.

This normal force or normal reaction on the girl is the weight she feels on her feet, as the elevator accelerates downwards.

R = mg + ma

R = m(g + a)

R = 32(9.8 - 0.85)

R = 32 (8.95)

R = 286.4 N

Therefore, the normal force acting on the girl is 286.4 N

i believe the answer is electric potential.
