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=0m. The block is then pulled to x=0. 5m and released from rest so that the block-spring system oscillates between x=−0. 5m and x=0. 5m, as shown in the figure. Which of the following claims is correct about the block’s period of oscillation?
