1. The problem statement, all variables and given/known data

I don't even know where to start on either of these two problems

A car of mass 474 kg travels around a flat,

circular race track of radius 197 m. The co-

efficient of static friction between the wheels

and the track is 0.123.

The acceleration of gravity is 9:8 m=s2 :

What is the maximum speed v that the car

can go without flying off the track?

It has a follow up too which I would really appreciate some help on!

The same car now travels on a straight track

and goes over a hill with radius 101 m at the

top.

What is the maximum speed that the car

can go over the hill without leaving the road?

A step by step outline would make my day!

Thanks

2. Relevant equations

A= V^2/ r

F= MV^2/ r

3. The attempt at a solution

I'm not sure how to go about tackling that problem, I tried just substituting 101 m in for the radius but that doesn't work.
