I dont have a particular question but there was a question on a quiz that totally stumped me, I am writing the test on this unit tomorrow so any help is appreciated.

the question was like.

A car is traveling in a circle with radius of

**17 metres, is .38**, what is the maximum speed the car could travel and maintain its course.

I figured it was something to do with friction force being = to centripetal force, but I dont have any formula's with

other than ff =

N.

And you dont know N or ff. I assume you have to find centripetal acceleration first?

is it ff=fc

mu N= (mv^2)/r

mu ma = (mv^2)/r

mu a= v^2/r

mu v^2/r = v^2/r

0.38 v^2/17 = v^2/17

Or something like that ??

Thank you.
