A girl sitting on a merry-go-round moves counterclockwise through an arc length of 3.15 m.
If the girl’s angular displacement is 1.82 rad, how far is she from the center of the merry-go-round?
Answer in units of m
Well, you get the movement as the arc in radians times the radius, which we need to find. Doing [tex]\frac{3.15}{1.82}=1.73[/tex], which is about [tex]\sqrt{3}[/tex] meters.
