  • question_answer
    An object is moving in a circle of radius 100 m with a constant speed of 31.4 m/s. What is its average speed for one complete revolution                                   [DCE 2004]

    A)             Zero    

    B)             31.4 m/s

    C)                 3.14 m/s

    D)                             \[\sqrt{2}\times 31.4\,\,m/s\]

    Correct Answer: B

    Solution :

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