    I'd appreciate it if you could help me with the following question:

    A bend in a level road forms a circular arc of radius 50m. A car travels around the bend at a speed of 14m/s without slipping occuring. What information does this give you about the value of the coefficient of friction between the tyres of the car and the road surface.

    Thank you in advance!

    For a body to move in circular motion, there has to be a centripetal force acting towards the center of the circle - provided in this case by the friction between the car tyres and the road. So if you write out the equations for centripetal force and frictional force and equate them (remembering the normal reaction on the car is going to be mg), you can calculate the coefficient of friction
