System A System B Systems A and B contain identical ideal springs and identical blocks that can slide along a surface of negligible friction. In system A, the surface is horizontal. In system B, the surface makes an angle 0 with the horizontal Initially, both blocks are at rest and in equilibrium. Each block is then pulled the same distance d in the direction shown in the figures and released from rest at t = 0. 76. For system A, when the block is halfway between its release position and its equilibrium position, the block's kinetic energy is K and the elastic potential energy of the spring-block system is U.
