A 7.0-kg block on a horizontal frictionless surface is attached to a light spring (force constant = 1.2 kN/m) .The block is initially at rest at its equilibrium position when a force of 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 a speed of 0.80 m/s.How much work is done on the block by the force P as the block moves the 8.0 cm?
