Question

An object is moving in a circle of radius 100 blank m with a constant speed of 31.4 blank m divided by s. What is its average speed for one complete revolution

  1. Zero  
  2. 31.4 blank m divided by s  
  3. 3.14 blank m divided by s  
  4. square root of 2 cross times 31.4 blank m divided by s  

The correct answer is: 31.4 blank m divided by s


    As the speed is constant throughout the circular motion therefore its average speed is equal to instantaneous speed
