Question

An object moves along a circular path of 7 m radius and completes its one
round in 10 sec. Calculate the velocity of the object.

Answer 1

Answer:

Zero

Explanation:

As the initial point and final point are same, the displacement is zero.

Velocity = Displacement / Time

Velocity = 0 / 10

Hence, velocity = 0

Answer 2

velocity=$\frac{displacement}{time}$

           =2$\pi$r/time

          =2*$\frac{22}{7}$*7/10

          =44/10

         =4.4 m/s
