A flat (unbanked) curve on a highway has a radius of 200 m. A car rounds the curve at a speed of 26.0 m/s.

What is the minimum coefficient of friction that will prevent sliding?

Our professor didn't even go over this, and it is way more complex than anything in the book. Plus, I am a communications major who got stuck. So please HELP!


What is the acceleration going around the curve? a= v^2/radius

Force friction = normal force*mu
That friction force has to equal m*accelerationabove.

Set them equal, where normal force is mg, and solve for mu.

  1. k(min)=(V^2/(gr))
    so, (26^2/(9.8*200))= .34
