Need help with Physics
What's the formula I need to solve this problem? I'm pretty sure it's an Fnet formula.
Calculate the maximum speed a car can successfully complete an 80 meter radius turn on a flat road if the coefficient of friction is .40.

My state dumbed down physics.. so idk.

μ=Ff/Fn Fn=mg Fc=(mv^2)/r Ff=Fc IIRC

C'mon flood, I know you know this.
