An engineer is trying to determine the maximum speed at which a vehicle travel around the curve without skidding. She know the coefficient of friction between the wheels and the road is 0.7 when the road is dry and 0.35 when the road is wet. She knows that the mass of the vehicle does not matter, but completes her calculations for a 700kg car. Answer the following questions for the case when the car is traveling at the maximum speed that will allow it to safely navigate the road in both wet and dry conditions. 330m Should she perform her calculations with the coefficient of friction for wet or dry pavement? In this case, what is the car's centripetal acceleration? m/s? In this case, what is the car's speed? m/s mph Could vehicles, obeying a speed limit of 80mph, navigate the curve on wet or dry pavement?
