Question: A 13-kg block (M) is released from rest on a frictionless incline that makes an angle of 20°, as shown in the figure below. Below the block is a spring that has a spring constant of 13500 N/m. The block momentarily stops when it compresses the spring by 5.4 cm. How far does the block move down the incline from its rest position to the stopping point?
