Please solve for work done by friction force
A 3.0-kg block is dragged over a rough horizontal surface by a constant force of 16 N acting at an angle of 37degree above the horizontal as shown. The speed of the block increases from 4.0m/s to 6.0m/s in a displacement of 5.0 m. What work was done by the friction force during this displacement?
