A 12-kg block (M) is released from rest on a frictionless incline that makes an angle of 28 degrees. Below the block is a spring that has a spring constant of 13500 N/m. The block momentarily stops when it compresses the spring 5.5 cm. How far does the block move down the incline from its rest position to the stopping point?
