Friction provides the force needed for a car to travel around a flat, circular race track. What is the maximum speed at which a car can safely travel if the radius of the track is 84.0 m and the coefficient of friction is 0.42?
Answers: 3
. In this case, the only force that applies for that is the static frictional force 
between the tires and the track. Then, we can write that:
and 
, we have:
and solving for 
, we get:
