## Homework Statement

A car approaches a curve that is banked at 20 degrees. The minimum speed for the curve is 20 m/s. The car's mass is 1000 kg. What is the radius of the curve if the coefficient of kinetic friction is 0.5 and the coefficient of static friction is 1.0?

## Homework Equations

I really don't know how to set up an equation for this problem. I understand that there are three forces acting upon the car, static friction, kinetic friction and force of gravity.

## The Attempt at a Solution

I understand that the coefficients both are interpreted to be:

(vector)fk = u(k)N

(vector)fs = u(s)N

(vector)Fg = mg
