How much work is done by frictional force on the block

Reference no: EM13651198

A 25Kg block on horizontal surface is attached to a light spring k=8.0KN/m the block is pulled 10 cm to the right from its equilibrium position and released from rest . When the block has moved 2.0 cm toward its equilibrium position , its kinetic energy is 12J . How much work is done by frictional force on the block as it moves the 2.0 cm?
