A truck of mass 9480 kg is traveling along a level road at an initial speed of 34.8 m/s and then slows to a final speed of 19.8 m/s. Find the total work done on the truck. I'm so lost on this problem. Newtons third law anyone? No friction is specified, I need a distance and a force to find the work 
Help me!! Thanks a ton.
