2) A 10kg box is headed towards a horizontal spring with spring constant k = 500- on a surface with MK - 0.3. The surface underneath the spring, however, is frictionless, so the box feels no friction as long as it is in contact with the spring. When the box is Im away from the spring, it has a speed of 3m. What is the maximum compression of the spring? Note that the box will not be moving at 3" when it initially contacts the spring, since it will have slowed down due to friction. Solve using an energy-work approach. (5 points k = 50ON V = 3 m " MK = 0 MK= 0. 3 10 kq I m
