An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the rate of 8.66 rev/s when the length of the chain is 0.600 m. When he increases the length to 0.900 m, he is able to rotate the ball only 5.93 rev/s. (a) Which rate of rotation gives the greater speed for the ball? 5.93 rev/s (b) What is the centripetal acceleration of the ball...

A child swings a tennis ball attached to a 0.633-m string in a horizontal circle above his head at a rate of 4.50 rev/s. (a) What is the centripetal acceleration of the tennis ball? (b) The child now increases the length of the string to 1.00 m but has to decrease the rate of rotation to 3.50 rev/s. Is the speed of the ball greater now or when the string was shorter? (c) What is the centripetal acceleration of the...

A child is swinging a 380-g ball at the end of a 69.0-cm-long string in a vertical circle. The string can withstand a tension of 16.0 N before breaking. (a) What is the tension in the string when the ball is at the top of the circle if its speed at that point is 3.90 m/s? (b) What is the maximum speed the ball can have at the bottom of the circle if the string does not break?
