A 4.4 kg block starts at rest and slides a distance d down a frictionless 32.0 degree incline, where it runs into a spring. The block slides an additional 0.16 m before it is brought to rest momentarily by compressing the spring, whose spring constant is 428 N/m. What is the value of d? What is the distance between the point of first contact and the point where the block's speed is greatest?
