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

In Formula One racing, cars often take corners at speeds in excess of 50 m s-1, and

so there is a very real danger of skidding.

(a)At a corner of radius 260m the track is banked at 20°. Calculate the maximum speed if no frictional force is required.

(b)'Downforce' is used to keep a car in contact with the track. The motion through the air produces a force perpendicular to the direction of travel, pushing the car onto the track. A racing car of mass 720 kg takes an unbanked corner of radius 550 m at a speed of 50 m s-1. The maximum frictional force is 0.4 x (reaction from track).Calculate the downforce necessary to prevent the car from skidding outwards.

2. Relevant equations

I know we have to use the Fc = mv^2 / r but not sure how ?! =/

3. The attempt at a solution

I have a Math exam tomorrow so I'm studying Math and it's not my doubt it's a doubt of one of my colleagues so You'd be doing him a BIG TIME favor if you help solving this :)

Thanks in Advance =D
