Question

A 0.18-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. Find the tension in the stick when the ball is (a) at the twelve o'clock and (b) at the six o'clock positions. (a) = (b) T=

Answer 1

Criver a maxs = 0.18 kg At 3 0 clock position tension is ign 9) Solve for twelve o' clock Newtonx second According to law blue =ts = four - 216 - Recrisange and some for tension at 12'0' clock T12 = Tarong = 16-0.18x9.8 b) Calculation for • 14. 236 N 60 Clock F = ma = To-mg = T3

for the tension Rearrange and solve 4. 'от со Те = Tз +ng = |ь N + b:19x-g Те - 1 -76 4N Ay
