Circular Motion Regarding Car Sliding on a Curve

[Neek 007]

Homework Statement

What is the maximum speed at which a car can negotiate a level curve of 100m without sliding if the coefficient of static friction is .70?

Homework Equations

F_fr≤ coefficient of frictionF_n
F=ma
F_c=mv²/r
Cir.=2pir
I know there are a couple more, but I'm not sure which ones.

The Attempt at a Solution

I know mass is not a factor here.
I think I'm supposed to plug in a formula into another formula. I'm thinking to plug in the force of friction formula(first formula) into F=ma.

Yup, that would work. And here's a couple of questions to help you along:

1. What else is F_n eqivalent to? (If you have to, draw a force diagram to help figure this out.)
2. What is a, given that the car is moving in a circle as it moves around the curve?

Ah, thank you so much. I got the right answer, 26.2 m/s.

Ok. I'm doing a small assignment about drifting at the moment! I can see that you figured out something, that might be similar to drifting.

My assignment is as following:

Describe some aspects of the phenomena drifting you'll find interesting, being a requirement that you use math, and or physics to explain.

Could you guys maybe help me out a little bit on this one?
