An inclined plane of angle 20 has a spring of force constant k = 500 N/m fastened firmly is parallel to the surface. A block of mass = 2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward towards the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?
