Question

A 615.00 kg race car is uniformly traveling around a circular race track. It takes the race car 20.00 seconds to do one lap around the 80.00 m radius circular track. What is the frequency of the race car's circular motion?

Answer 1

Answer:

The value is  $f = 0.05 \ Hz$

Explanation:

From the question we are told that

     The mass of the car is  $m = 615 \ kg$

      The period of the circular motion is  $T = 20 \ s$

      The radius  is $r = 80 \ m/s$

Generally the frequency of the circular motion is  

       $f = \frac{1}{T }$

=>    $f = \frac{1}{ 20 }$

=>    $f = 0.05 \ Hz$
