PROBLEM 2: A light ideal spring is attached to a block of mass m2 that sits at rest on an oily, frictionless table. A block of mass m; is then launched with an initial speed of v, at the spring attached to block m2. Assuming no energy is lost due to friction, find (a) the speed of the blocks at the moment when the spring is maximally compressed, and (b) the fraction of m;'s initial energy that is stored in the spring at that point, and (c) the speed of both blocks after m, detaches (bounces back) from the spring again.

PROBLEM 2: A light ideal spring is attached to a block of mass m2 that sits at rest on an oily, frictionless table. A block of mass m, is then launched with an initial speed of v, at the spring attached to block m2. Assuming no energy is lost due to friction, find (a) the speed of the blocks at the moment when the spring is maximally compressed, and (b) the fraction of m¡'s initial energy that is stored in the spring at that point, and (c) the speed of both blocks after m, detaches (bounces back) from the spring again. Part (2) Solve this numerically, based on your equations for the above problem. Given that m, is 3.77 kg, mjis 3.56 kg, and vo is 4.7 m/s, find the final velocity (in m/s) of the spring block (m2) after the bounce as described in part (c) Part (3) Is the collision in the problem above an elastic, inelastic, or perfectly elastic collision? How do you know? Explain your answer.
