Question
(a) Determine the ball's speed.1 m/s
(b) If, instead, the ball is revolved so that its speed is 4.0 m/s,what angle does the cord make with the vertical?
2°
(c) If the cord can withstand a maximum tension of 9.8 N, what is the highest speed at which the ballcan move?
3 m/s A 0.50 kg ball that is tied to the end of a 1.5 m light cord is revolved in a horizontal planewith the cord making a 30degree angle, with the vertical. (a) Determine the ball's speed. 1 m/s (b) If, instead, the ball is revolved so that its speed is 4.0 m/s,what angle does the cord make with the vertical? 2degree (c) If the cord can withstand a maximum tension of 9.8 N, what is the highest speed at which the ballcan move? 3 m/s
Explanation / Answer
T = 9.8 N
T cos = 4.9
cos =0.5
= 60
