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 7.64 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 6.13 rev/s. (a) Which rate of rotation gives the greater speed for the ball? O 6.13 rev/s O 7.64 rev/s (b) What is the centripetal acceleration of the ball at 7.64 rev/s? m/s2 (c) What is the centripetal acceleration at 6.13 rev/s? m/s2
