A car of mass 900.0 kg accelerates away from an intersection on a horizontal road. When the car speed is 49.7 km/hr (13.8 m/s), the net power which the engine supplies is 4300.0 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.

a=P/mv=4300/900•13.8=0.35 m/s²
