1. The problem statement, all variables and given/known data
A car of mass 1164kg was travelling around a 288m radius corner at a speed of 10.8m/s. What was the magnitude of the fiction force required to maintain the vehicles path?

2. Relevant equations
F=ma
I have no idea after that

3. The attempt at a solution
I found mg = 11407.20

Can someone please explain about frictional force, I find this very hard, I have read and reread a lot of info but I just don't get it. Especially when I have to apply it to problems and I don't have the coefficient.

You don't need to know anything about friction to solve this. You just need to know the acceleration of the car, wich is in circular motion with constant speed.
The only force that can cause this acceleration is the friction force.

Anyone?
