To find the girl's mass, we can use the formula for centripetal force:
where:-
is the centripetal force,-
is the mass of the girl,-
is the tangential speed,-
is the radius of the circular path.Given:-
-
-
We need to solve for
:
Substitute the given values into the equation:
Calculate the denominator:
Now, calculate the mass:
Therefore, the girl's mass is approximately
.
