A 0.50 kg ball that is tied to the end of a 1.7 m light cord is revolved in a horizontal plane with the cord making a 30° angle, with the vertical (See Fig. P7.52.)http://www.webassign.net/sercp/p7-52.gif

(a) Determine the ball's speed.

2.19347 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?

(c) If the cord can withstand a maximum tension of 9.1 N, what is the highest speed at which the ball can move?
