1. The problem statement, all variables and given/known data 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. 2. Relevant 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 3. The attempt at a solution Can someone please help me understand where the [6.468] came from?
