Acar of mass 960.0 kg accelerates away from an intersection on a horizontal road. when the car speed is 51.1 km/hr (14.2 m/s), the net power which the engine supplies is 3700.0 w (in addition to the extra power required to make up for air resistance and friction). calculate the acceleration of the car at that time.
