A 5 kg block is placed near the top of a frictionless ramp, which makes an angle of 30? degrees to the horizontal. A distance d = 1.3 m away from the block is an unstretched spring with k = 3 * 10 3 N/m. The block slides down the ramp and compresses the spring. Find the maximum compression of the spring.
