Part B - Finding the maximum allowable acceleration
Suppose that the tires are capable of exerting a maximum friction force of 1360 lb. If the car is traveling at 58.5 ft/s and the curvature of the road is p= 450 ft.
what is the maximum tangential acceleration that the car can have without sliding?
Express your answer to three significant figures and include the appropriate units.
