Physics 1 One of the main topics this week is circular, or centripetal, motion looking at its acceleration and associated force. For the centripetal force, is this a NEW force, explain? Often times, CENTRIFUGAL force is used in describing circular motion, is this an appropriate alternative to centripetal force, explain? One example of centripetal force is its application to curves - flat & banked - in terms of the maximum speed one can make the curve, what happens when the...

Suppose that the coefficient of friction between a car's tires and the road is 0.600 when the road is dry and 0.350 when the road is wet. If on a certain curve the maximum speed the car can go without slipping is 42.0 m/s when the road is dry, what is the maximum speed the car can go on the same curve without slipping when the road is wet?
