A car of mass 880 kg880\text{ kg} travels along a straight horizontal road with its engine working at a constant rate of P WP\text{ W}. The resistance to motion is 700 N700\text{ N}. At an instant when the car’s speed is 16 m s116\text{ m s}^{-1} its acceleration is 0.625 m s20.625\text{ m s}^{-2}. Find the value of PP.
