4. Suppose a block of mass m slides over a surface with kinetic friction coef- ficient k towards a spring with spring constant k. The block reaches the spring with spring with speed vo. (20 points) (a) How far is the spring compressed at maximum compression? Give your answer in terms of m, k, pk, and vo. 13 (b) What is an expression for the maximum value that vº could be in order for the spring to remain maximally compressed, no matter what material the block and surface are? Give your answer in terms of m, k, pk. Hint: the coefficient of static friction is always greater than the coefficient of kinetic friction.
