For rear-wheel drive cars, the engine turns the rear wheels, whereas the front wheels rotate solely because the car moves. When such a car accelerates along a horizontal road, the friction

Step-by-step solution

For a rear-wheel drive car, the engine applies a torque to the rear wheels, causing them to tend to slip backward at the point of contact with the road. To oppose this slipping, the static friction on the rear wheels acts in the forward direction. This forward friction provides the driving force for the car. The front wheels are not driven by the engine. They are pushed forward by the axle. To make them roll and provide angular acceleration, friction at the point of contact must act in the backward direction. Since
