The rear-wheel-drive car can go from rest to 60 mph in Δt = 8 s. Assume that its wheels are identical, with their geometric centers coinciding with their mass centers. Let Favg be the average friction force acting on the system during Δt due to contact with the ground. Modeling the car and the wheels as rigid bodies, does the value of Favg change whether or not we account for the rotational inertia of the wheels? Why?
