A 1200 kg car accelerates to the right at 7m/s2 along a special frictionless track. Determine the magnitude and direction of the force the engine exerts to accelerate the car?
A wind blows heavy winds into the car's path.As a result the car's acceleration slows to 4.5m/s2. If the engine is exerting the same force it was in part a, how much force does the wind exert on the car to slow acceleration.
