On an icy winter day, the coefficient of friction between thetires of a car and the roadway is reduced to one-half of its valueon a dry day. As a result, the maxiumum speed at which acurve of radius R can be safely negotiated is reduced. Whatpercentage of the dry day speed is safe on an icy day?
Thank you for your help!!

      If ? is the friction between the tires and the road
      the maximum speed with which a curve can be takenwithout skidding
             V =
                   R - radius
      Given
      the friction is reduced to half its value on a dryday

          ?ice = ?dry /2
      maximum speed on a icy winter day is
            V i =

      % of maximum speed on icy day to that of dry day
             * 100
