Question
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 θ = 30° angle with the vertical.
An illustration shows a ball suspended from a string. The string forms an angle θ with the vertical as its top end is held stationary in space while the ball moves along a horizontal circular path below. The center of the circular path is shown to be directly below the top end of the string.
(a) Determine the ball's speed.
m/s
(b) If, instead, the ball is revolved so that its speed is 3.8 m/s, what angle does the cord make with the vertical?
°
(c) If the cord can withstand a maximum tension of 9.6 N, what is the highest speed at which the ball can move?
m/s
m/s
(b) If, instead, the ball is revolved so that its speed is 3.8 m/s, what angle does the cord make with the vertical?
