A block of mass 12.0 kg is initially sitting at rest on a 30.0o incline. There is a spring mounted to the ramp with spring constant k = 13500 N/m. The block is released to slide down the incline and comes to a stop momentarily after the spring has been compressed a distance of 5.5 cm. a) How far along the incline has the block moved from the point at which it was released to this point at which it come to rest momentarily? b) What is the speed of the block as it first touches the spring?
