What angle does the cord make with the vertical

Reference no: EM13662286

A 0.50 kg ball that is tied to the end of a 1.2 m light cord is revolved in a horizontal plane by the cord making a 30° angle, with the vertical.

a) Decide the ball's speed.

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 9.3 N, what is the highest speed at which the ball can move?
