Circular Motion: A police car runs around a turn of radius 35 m at a constant speed of 45 m/s.
a. What is the acceleration of the car while going around the turn at a constant speed?
b. If the car goes around an entire circle at this speed what is the time it takes for one complete revolution?
c. What is the frequency of revolution in cycles per second or Hertz, Hz, for this car going repeatedly around the circle at the same fixed speed?
