A truck of mass 8610 kg is traveling along a level road at an initial speed of 33.5 m/s and then slows to a final speed of 18.5 m/s. Find the total work done on the truck. I thought that I was just supposed to use W= Change in KE so W= (.5)(8610)(18.5)^2 - (0.5)(8610)(33.5)^2 but when I do this I get 3357900 J and it says that is wrong.
