2. (6 points) (Comparable to 6.31 6.43] Solve this problem using work-energy methods. A bowling ball of mass m moves at initial speed up on a flat and frictionless surface. It hits a massless spring which has spring constant k. (a) Find an expression for d, the amount the spring will compress? {bl In your answer to part (a), verify that your expression for d has the correct units or dimensions
