A group of highway engineers has designed a curved section of a road. The speed limit on this road is 30.0 m/s (roughly 60 mph). The radius of the curve is designed so that the road is barely safe to drive on if µ = 1.00. If it rains or freezes and µ drops to 0.500, then what would be the maximum safe speed in those conditions?
