## Homework Statement

I have a general question about circular motion of a car on a flat curve.

What must the static friction koefficient be if the car can make the swing by 60km/h?

Thank you,

## Homework Equations

- We have to follow Newtons 2nd law.

- Fcentripetal = m*(v^2/r)

known stats:

r= 150m

v= 16,67m/s

g= 9,81

## The Attempt at a Solution

mg = v2/r /g

m= v2/r*g

m= ((16,67*16,67)/(150*9,81))

m= 0.189

Need probably help here, not sure if I did do the equations right.
