Evaluate what is the net work done on the box

Reference no: EM13646132

A 35-kg box is pulled with a 55-N force at 38 degrees above the horizonal surface. Coefficent of kinetic friction between the box and the horizonal surface is .15. The distance the box is pulled is 25m. How much work is done by the boy, what is the work done by the frictional force, and what is the net work done on the box?
