1. The problem statement, all variables and given/known data A truck pushes a car by exerting a horizontal force of 500 N on it. A frictional force of 300N opposes the cars motion as it moves 4m. Calculate the work done on the truck. 2. Relevant equations work = force x distance 3. The attempt at a solution work done = 300N x 4 m = 1200J work right?
