A girl running around a circular track of radius 200 m completes one revolution in 10 minutes. What is her average velocity in one full
revolution

v = 2 m/s

Explanation:

First, we find the angular velocity of the girl by using the following formula:

Now, for the average velocity of the girl we can use the following formula:

where,

r = radius = 200 m

therefore,

v = 2 m/s
