Question

A 57.0 kg woman is in an elevator accelerating upward at 1.25 m/s². What is the normal force acting on her? [?] N Don't forget her weight!​

Answer 1

The normal force 630.4 N

Step-by-step explanation:

Given:

m = 57.0 kg

a = 1.25 m/s²

g = 9.81 m/s²

___________

N - ?

Since the elevator is moving with acceleration UP, the reaction of the support:

N = m· (g + a)

N = 57.0·(9.81 + 1.25) ≈ 630.4 N
