A 19kg block on a horizontal surface is attached to a light spring (F constant= 3.0 kgN/m). The block is pulled 6.3cm to the right from the equilibrium position and released from rest. When the block has moved 12cm towards its equilibrium position, its kinetic energy is 37J. How much work is done by the frictionless force on the block as it moves the 7 cm?
