Student Y is at rest while sitting on a swing. Student X stands behind student Y and provides an initial applied force on student Y. Student Y's position on the swing then oscillates. Which of the following claims is correct about student Y? {Ans: If student X applies a greater force on student Y, the total mechanical energy of the student Y-Earth system will increase compared to the original situation.}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
