A block of mass 0. 5kg on a horizontal surface is attached to a horizontal spring of negligible mass and spring constant 50n/m. The other end of the spring is attached to a wall, and there is negligible friction between the block and the horizontal surface. When the spring is unstretched, the block is located at x=0. 0 m. The block is then pulled to x=0. 5 m and released from rest so that the block-spring system oscillates between x=−0. 5 m and x=0. 5 m, as shown in figure 1. A free-body diagram of the object at a particular location is shown in figure 2. Based on the free-body diagram, at which of the following locations could the block be?.
