A 3.20 kg block starts at rest and slides a distance d down a frictionless 30.0° incline, where it runs into a spring (Fig. 8-6). The block slides an additional 19.5 cm before it is brought to rest momentarily by compressing the spring, whose spring constant k is 430 N/m.

(a) What is the value of d?

(b) What is the distance between the point of first contact and the point where the block's speed is greatest?
