An athlete swings a 6.20-kg ball horizontally on the end of a rope. The ball moves in a circle of radius 0.970 m at an angular speed of 0.770 rev/s. (a) What is the tangential speed of the ball? m/s (b) What is its centripetal acceleration? m/s² (c) If the maximum tension the rope can withstand before breaking is 102 N, what is the maximum tangential speed the ball can have? m/s
A 0.50-kg ball that is tied to the end of a 2.0-m light cord is revolved in a horizontal plane, with the cord making a 0 = 30° angle with the vert € (a) Determine the ball's speed. m/s (b) If, instead, the ball is revolved so that its speed is 4.5 m/s, what angle does the cord make with the vertical? (c) If the cord can withstand a maximum tension of 9.5 N, what is the highest speed at which the ball can move? m/s
