How many revolutions does a wheel with angular speed (88 rad s ⁻¹ ) make in one second?

Options

  1. A7
  2. B14
  3. C28
  4. D44

Correct answer

B. 14

Step-by-step solution

Angular speed of wheel, ( =88 rad s ⁻¹ ) ( ) Number of revolution per second is equal to its frequency (f ). i.e. ( =2 f ) ( f= 2 = 88 2 22 7 = 88 7 2 22 =14 rev / s )
