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 39 degree above the horizontal. The crate has mass 158 kg. You are sitting inside the crate (with a flashlight); your mass is 54 kg. 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 67degree with the top of the crate.
