AP Physics 1: SHM Math Practice uestion 1: 50 N/m Wellllll0 0.5 kg X =-0.3 m x=0m X = 0.3 m A block of mass 0.5kg on a horizontal surface is attached to a horizontal spring of negligible mass and spring constant 50 N/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 m. The block is then pulled to x = 0.3 m and released from rest so that the block-spring system oscillates between x = -0.3 m and x =0.3 m. What is the magnitude of the acceleration of the block and the direction of the net force exerted on the block when it is located at x = 0.3 m
