Problem 1 A 5.0 kg box has an unknown initial velocity, Vo, when it runs into a light spring of force constant, k = 5000 N/m, and compresses the spring to a maximum distance of 5.0 cm. The kinetic coefficient of friction between the block and the surface is 0.25. Use the work-energy theorem to find the initial velocity of the block. Do not use conservation of mechanical energy to solve this problem. Show all work for full credit.
