Question

A stunt woman of mass m falls into a net during the filming of an action movie. Assume she experiences upward acceleration magnitude aaa while touching the net.
What is the correct expression for the normal force magnitude exerted on the stunt woman?
Consider upward as the positive direction.

Answer 1

Answer:

M= F^n / a+g

Explanation:

This shows correctly Newton’s second law, where sum of forces is divided by mass is equal to acceleration. Also mass can’t be negative so F^n is positive.

Answer 2

Answer:

$\frac{Fn-mg}{m\\}= a$

Explanation:
