A m = 8 kg blоck оn а hоrizontаl frictionless surfаce is attached to a light spring (force constant = 0.85 kN/m). The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block, as shown. Starting from the "One Equation to Rule Them All" (the energy equation) and showing all steps, find the speed of the block when it is 13 cm from its equilibrium position. (Round to nearest answer)
