A2000 kg pick up truck experiences a 150 n of air resistance and a 200 n of rolling resistance(this is due to the deformation of the tires). how large is the force exerted by the road on the drive wheels if the car is traveling (a) at a constant speed of 30 m/s and (b) with an acceleration of 0.1 m/s^2 .
