You are tasked with setting a speed limit on an exit ramp from a highway. You are told that the radius of this ramp (road) is 28 m and friction between the road and automobile tires can support a maximum acceleration of 4.5 m/s2. Friction helps keep an automobile from flying off the road. Assume an unbanked horizontal road. (8 pts) (a) what is the maximum speed (in m/s) an automobile can have without flying off the road
