If the maximum tension the rope can withstand before breaking is 11 N,what is the maximum angular speed of the?
IP A person swings a 0.51 kg tether ball tied to a 4.6 m rope in an approximately horizontal circle.
If the maximum tension the rope can withstand before breaking is 11 , what is the maximum angular speed of the ball?
=________rad/s
If the rope is shortened, does the maximum angular speed found in part A increase, decrease, or stay the same?
11 N = 0.51 x (v^2/r)
11/0.51 = 21.568
21.568 x 4.6 = v^2 = 99.2156, sq-root = v = 9.96 m/s
9.96/4.6 = rad/s = 2.165 rad/s
If the rope is shortened, does the maximum angular speed found in part A increase, decrease, or stay the same?
stays the same
