Answer:
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,
<u>v = 2 m/s</u>

Where
T is the time taken by the planet to orbit the sun
M is the mass of sun
G is the universal gravitational constant
a is the distance of planet form the sun
