The angular velocity of a bicycle wheel is 50 . rev/min. Suppose the angular velocity of the wheel increases to 100 rev/min in 10 seconds, and then comes to rest in 8.4 seconds after that. Calculate the angular acceleration during these two periods of time. What is the angular acceleration of a phonograph turntable if it reaches its angular ... ................
