A car of mass 920.0 kg accelerates away from an intersection on a horizontal road. When the car speed is 48.2 km/hr (13.4 m/s), the net power which the engine supplies is 5900.0 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.

power=force*velocity=mass*acceleration*velocity
acceleration=power/(mass*velocity)
acceleration=power/(mass*velocity)
