Question

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 7.27 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 6.21 rev / s. Which rate of rotation gives the greater speed for the ball? What is the centripetal acceleration of the ball at 7.27 rev / s? What is the centripetal acceleration at 6.21 rev / s? This figure represents the total acceleration of a particle moving clockwise in a circle of radius r = 2.20 m at a certain instant of time. For that instant, find the radial acceleration of the particle. For that instant, find the speed of the particle. For that instant, find its tangential acceleration.
