## Homework Statement

A 0.22-kg ball on a stick is whirled on a vertical circle at a constant speed. When the ball is at the three o'clock position, the stick's tension is 19 N.

## Homework Equations

mass m = 0.22 kg

tension in 3'o clock position T = 19 N

tension in 12 'o clock position T ' = T-3mg

= 19 - 6.468

= 12.532 N

tension in 6 'o clock position T " = T + 3mg

= 19 + 6.468

= 25.468 N

## The Attempt at a Solution

Can someone please help me understand where the [6.468] came from?
