<u>Answer</u>:
The coefficient of  static friction between the tires and the road is 1.987
<u>Explanation</u>:
<u>Given</u>:
Radius of the track, r =  516 m
Tangential Acceleration  =  3.89 m/s^2
=  3.89 m/s^2
Speed,v =  32.8 m/s
<u>To Find:</u>
The coefficient of  static friction between the tires and the road = ?
<u>Solution</u>:
The radial Acceleration is given by, 




Now the total acceleration is 
 
 
=>
=>
=>
=>
The frictional force on the car will be f = ma------------(1)
And the force due to gravity is W = mg--------------------(2)
Now the coefficient of  static friction is

From (1) and (2)


Substituting the values, we get
