Find the total work done on the truck

Reference no: EM13274842

A truck of mass 7,000 kg is traveling along a level road at an initial speed of 20 m/s. The driver then shifts into neutral so that the truck is coasting, and the truck gradually slows to a final speed of 11 m/s.

(a) Find the total work done on the truck. (in J)

(b) What force(s) do this work on the truck? (There may be more than one. Select all that apply.)

air drag

friction from the road

gravity

the normal force from the road

(c) The final kinetic energy of the truck is less than its initial kinetic energy. Where does this energy go? (Select all that apply.)

heat within the vehicle

heat within the road

heat within the air gravitational

potential energy
