1. The problem statement, all variables and given/known data A boy pulls his wagon of mass 25.0kg at a constant velocity a distance of 20.0m. the wagon's handle makes an angle of 40.0° with the ground while the boy is pulling on it with a force of 60.0N. The coefficient of friction is 0.214. how much work did the boy do on the wagon 2. Relevant equations W=FdCos(theta) 3. The attempt at a solution Not sure where to start. Im not sure where the friction fits in.
