Car on a Level Corner (continued...)

To Summarize

When a car turns a corner on a flat road surface the force of friction supplies the necessary inward force. We can write this in the following equations:


Practice

  1. A car turns a level corner of radius 120 m. If the coefficient of static friction between the car's tires and the road surface is 0.80, what is the maximum speed for which skidding does not occur? m/s .
  2. What is the sharpest radius turn that a sport's car of mass 2000 kg moving at 22 m/s can make without skidding if the coefficient of static friction between the car's tires and an icy road surface is 0.55? m.
