- Homework Statement
- You are pushing a 53kg crate with an acceleration of 1m/s^2 up a ramp. The ramp makes an angle of 22° above the horizontal. If your applied force is 524N, what is the kinetic coefficient of friction between the crate and the ramp?

- Relevant Equations
- μ = Ff/Fn

Fn = m X g X cos θ

Fnet = Fa – mg sin θ +or- μmg cos θ

Fn = 53 X 9.81 X cos 22

Fnet = 524 – 53 X 9.81 sin 22 + μ X 53 X 9.81 cos 22

Fnet = 524 – 53 X 9.81 sin 22 + μ X 53 X 9.81 cos 22
