38. 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 8.00 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 6.00 rev/s. (a) Which rate of
rotation gives the greater speed for the ballP (b) What is
the centripetal acceleration of the ball at 8.00 rev/s
(c) What is the centripetal acceleration at 6.00 rev/s?
