A race car moves along a circular track at a speed of 0.512 m/s. If the car's centripetal acceleration is 15.4 m/s2, what is the distance between the car and the center of the track?

The radius is    

Explanation:

From the question we are told that

      The speed at which the race car moves is

       The centripetal acceleration is  

Generally the centripetal acceleration is mathematically represented as

=>        

=>        

i believe the answer is a
