A block of mass (M = 11.8 , ext{kg}) is held at rest at the bottom of a (21.7^circ) incline. It has been placed in contact with a spring ((k = 2504 , ext{N/m})) that has been compressed (25.5 , ext{cm}) from its unstretched position. When the block and spring are released, the block goes a total distance (D) up the incline before coming to rest. The coefficient of kinetic friction between the block and the incline is (0.351).
