Centrepetal Problem help PLEASE!
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
A= V^2/ r
F= MV^2/ r
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.
