Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:
[tex]Angular\ Velocity =\omega= \frac{Angular\ Distance\ Covered}{Time\ Taken}\\\\\omega = \frac{1\ revolution}{10\ min}\frac{1\ min}{60\ s}\frac{2\pi\ rad}{1\ revolution}\\\\\omega = 0.01\ rad/s[/tex]
Now, for the average velocity of the girl we can use the following formula:
[tex]Average\ Velocity = V = r\omega\\V = (200\ m)(0.01\ rad/s)\\[/tex]
where,
r = radius = 200 m
therefore,
v = 2 m/s
