Name:__________________________________________Section____
A block of mass ? = 12.0 kg is released from rest on an incline angled at θ = 30 degrees. The block slides down and incline of length ? = 1.40 m along the incline, which has a coefficient of kinetic friction between the incline and the block of ?? = 0.180. The block then slides on a horizontal frictionless surface until it encounters a spring with a spring constant of ? = 205 N/m. Refer to the figure below.
(a) Calculate the work done on the block by each force acting on the block as it slides down the inclined plane.
