A block on a horizontal surface is attached to a horizontal spring of spring constant 50N/m. The other end of the spring is attached to a wall. The block is initially at the equilibrium position of the block-spring system, as shown in the figure. The block is then moved to a position of x=60cm and released from rest so that the system oscillates. A student predicts the kinetic energy of the block-spring system as a function of the block's horizontal position as shown in Graph 1. When an experiment is conducted, the block does not make a complete oscillation because frictional forces were not considered in the student's prediction. Data is collected about the actual kinetic energy of the block-spring system as a function of the block's horizontal position and is used to create Graph 2. {Ans: Use Graph 2 to determine the spring potential energy stored in the system at the instant the block is no longer in motion. Subtract this value from the maximum predicted kinetic energy of the block that can be determined from Graph 1.}Student Y is at rest while sitting on a swing.
