3. Engineers are building a road with a curve in it. They want to maintain a 60 mph speed limit throughout the curve without the vehicles sliding off the roadway. a. If the coefficient of friction between the roadway and the rubber tires is u=.450, what radius does the curve need to be to keep the vehicles safely on the highway? b. If engineers want to keep the curve's radius, but lower the speed limit to 45 mph what does the minimum coefficient of friction need to be? a b
