Asked by Josh
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.

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