Hi all!
A professional race-car driver is asked to make 2 different "quarter-circle" turns on a racing track.
He completes them at the highest possible constant linear speed (he is well familiar with the car and the road so it's an easy task for him).
Turn 1: Radius is R1=20m. Linear velocity measured was V1.
Turn 2: Radius is R2=45m. Linear velocity measured was V2. (V2 > V1)
Question: According to Circular Motion Model (V2=A*R)
should we expect to arrive at the same Centripetal Acceleration (A) in both cases? (Suppose air resistance and is not a factor).
I guess the question is more about the behavior of Force generated by friction and how, if at all, the linear speed affects it.
