Moving on a straight and horizontal stretch of road, the rear-wheel-drive car shown can go from rest to 60 mph in Δt = 8 s. The car weighs 2570 lb (the weight includes the wheels). Each wheel has diameter d = 24.3 in., mass moment of inertia relative to its own center of mass IG = 0.989 slug·ft2, and the center of mass of each wheel coincides with its geometric center. Determine the average friction force Favg acting on the car during Δt .In addition, if the wheels roll without slip, for each wheel, determine the average moment Mavg, computed relative to the wheel’s center, that is applied to the wheel during Δt.
