A steel washer is suspended inside an empty shipping crate from a light string attached to the top of the crate. The crate slides down a long ramp that is inclined at an angle of 38∘ above the horizontal. The crate has mass 171kg . You are sitting inside the crate (with a flashlight); your mass is 62kg . As the crate is sliding down the ramp, you find the washer is at rest with respect to the crate when the string makes an angle of 56∘ with the top of the crate.

What is the coefficient of kinetic friction between the ramp and the crate?
