Q1Newton's Laws of MotionEnergy, Work and PowerFree sample

A car of mass $700\text{ kg}$ is travelling along a straight horizontal road. The resistance to motion is constant and equal to $600\text{ N}$ .

(i)

Find the driving force of the car’s engine at an instant when the acceleration is $2\text{ m s}^{-2}$ .

(ii)

Given that the car’s speed at this instant is $15\text{ m s}^{-1}$ , find the rate at which the car’s engine is working.
