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

A circular disk of radius 0.200 m rotates at a constant angular speed of 1.50 rev/s. What is the centripetal acceleration (in m/s^ 2 ) of point on the edge of the disk?
George swings a ball around him, in uniform circular motion. The circle's radius is r. George inadvertently releases the string, and the ball goes outward. He catches the string again, and now the ball goes around him at a new rotation rate, with a new radius r + Δr. Calculate the new rotation rate (in rev/s). r = 3.0 m Δr = 1.0 m Original rotation rate = ωi = 1.1 rev/s The ball's mass is m = 160 grams
I am having trouble with a 3 d motion problem. The problem is as follows, "A point on a rotating turntable 20.0 cm from the center accelerates from rest to a final speed of 0.600 m/s in 1.80 s. At t = 1.29 s, find the magnitude and direction of each of the following." The problem asks me to find the radial acceleration, the tangential acceleration, and the total acceleration of the point. Thanks for the help.

Jason is lucky enough to be selected to take part in a Wheel of Fortune game. The Wheel of Fortune, which is 46.0 cm in radius, comprises 8 equal segments with only 3 prizes, i.e. a smartphone, a laptop, and a $100 cash as shown in Figure 2. With the starting position of the black pointer at the border of red and yellow segments, Jason spins the Wheel of Fortune with an initial tangential speed of 5.80 m/s in a clockwise direction. It is found that the Wheel of Fortune is slowing down at a rate of 1.05 rad/s². Determine(i) the initial angular speed of the wheel, and the time the wheel will remain spinning, (ii) the angular displacement of the wheel, (iii) which segment the pointer will point at when the wheel stops
