Problem
A 4.0kg crate is released from rest at the top of a 5.0m-long ramp that makes an angle of 15∘ with the horizontal. The coefficient of kinetic friction between the crate and the ramp is 0.12. Air resistance is negligible.
(a) Calculate the magnitude of the acceleration of the crate as it slides down the ramp.
(b) Determine the time required for the crate to reach the bottom of the ramp.
(c) Find the speed of the crate at the bottom of the ramp.
