A1.0-m roulette wheel reaches a maximum angular speed of 18 rad/s before it begins decelerating. after reaching this maximum angular speed, it turns through 35 revolutions (220 rad) before it stops. how long did it take the wheel to stop after reaching its maximum angular speed?

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 8.13 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 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
