The graph below shows a plot of angular acceleration in rad/s2 versus time from t = 0 s to t = 8 s. The angular velocity at t = 0 s is a = 5 rad CCW. The angular velocity, w, at t = 8 s is Angular Acceleration vs. Time 4 2 8 -2 -4 -6 -8 Time (s)

An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s). If a particular disk is spun at 968.7 rad/s while it is being read, and then is allowed to come to rest over 0.301 seconds, what is the magnitude of the average angular acceleration of the disk? rad average angular acceleration: s2 If the disk is 0.12 m in diameter, what is the magnitude of the tangential acceleration of a point 1/7 of the way out from the center of the disk? m tangential acceleration: s2 about us privacy policy terms of use contact us help careers tv W MacBook Air F12 F10 F9 80 000 000 F4 F3
