A horizontal spring is set up like the one in Fig. 11-3. It has an elastic constant of 100.0 N/m. A 2.50-kg mass, sitting on a frictionless horizontal surface, is attached to the end of the spring. The mass is displaced 25.0 cm to the right and released, whereupon it oscillates in SHM. Determine its acceleration (magnitude and direction) and its velocity (magnitude and direction) when it first reaches a location 20.0 cm to the left of the equilibrium position.
