A 2-kg block travels from the top of a plane inclined 25o with the horizontal compressing a spring at the bottom of the incline with an initial speed of 0.65 m/s. Due to the motion of the block, the spring was compressed by 0.2 meters. The spring has a k of 100 N/m and the coefficient of friction between the block and the incline is 0.40. How much work was done by friction on the block?
