A 25.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30? above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coeffcient of kinetic friction between the crate and the ramp is 0.400 and the constant of the spring is k = 5000 N/m. How far does the crate compress the spring?
