A 7.0kg block on a horizontal frictionless surface is attachedto a light spring (force constant =1.2kN/m). The block is initiallyat rest at its equilibrium position when a force (magnitude P)acting parallel to the surface is applied to the block, as shown.When the block is 8.0 cm from the equilibrium position, it has aspeed of 0.80 m/s. How much work in J is done on the block by theforce P as the block moves the 8.0cm?
