If a drag racing car with a mass of 1000 kg can accelerate from rest to a speed of 120 m/s in 400 m what is (a) the work done by the driving force, (b) the value of the driving force if it is assumed to be constant?

Determine (a) the kinetic energy and (b) the velocity of an object of mass 10 kg when it has moved from rest under the action of a force of 20 N a distance of 4.0 m.
