This indeed is true, a hero is someone who can against very bad odds unify a country that can be torn or just be generally very heterogenous. There have been many cases of such heroes in the past where they would unify a certain country or society under the same banner.
The tension in the swing's chain at the bottom of the swing is 178.35 N.
The given parameters:
- Mass of the girl, m = 27 kg
- Speed of the girl, v = 3 m/s
- Radius of the circle, r = 4 m
The tension in the swing's chain at the bottom of the swing is calculated as follows;

Thus, the tension in the swing's chain at the bottom of the swing is 178.35 N.
