A typical laser disc can spin as fast 1800 RPM. The angular speed is therefore 2pi* 1800/60=60 pi rad/s. If it takes 17s to stop the rotation from this top speed, how much change is in angle displacement (i.e. The change in angle measured in radians)? Report the result in absolute value.
A centrifuge takes 100.0s to spin up from rest to it's final angular speed with constant acceleration. A point is located 10.0cm from the axis of rotation of the centrifuge moves with a speed of 250.0m/s when the centrifuge is at full speed. (a) What is the final angular speed? (b) What is the average angular acceleration of the centrifuge as it spins up? (c) How many revolutions does the centrifuge make as it goes from rest to it's final...
An electric motor operates at 1800 rpm. What is the linear speed of a point 55mm from the axis of rotation? What is its centripetal acceleration?
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 528.8 rad s while it is being read, and then is allowed to come to rest over 0.435 seconds, what is the magnitude of the average angular acceleration of the disk? Number rad/s If the disk is 0.12 m in diameter, what is the magnitude of the tangential acceleration of a point 1/9...
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 294.3 rad / s while it is being read, and then is allowed to come to rest over 0.234 seconds, what is the magnitude of the average angular acceleration of the disk? AND If the disk is 0.12 m in diameter, what is the magnitude of the linear acceleration of a point 1/8...
During the time a compact disc (CD) accelerates from rest to a constant rotational speed of 477 rev/min, it accelerates with an angular acceleration of 794 rad/s2 . What is the angular displacement of the CD? answer is pi/2 rad
The angular speed of digital video discs (DVDs) varies with whether the inner or outer part of the disc is being read. (CDs function in the same way.) Over a 129 min playing time, the angular speed varies from 564 rpm to 1610 rpm . Assuming it to be constant, what is the angular acceleration (in rad/s2) of such a DVD?

(a) What is its angular acceleration in rad/s2? rad/s² (b) What is the tangential acceleration, in m/s, of a point 10.55 cm from the axis of rotation? O m/s2 (c) What is the radial acceleration, in m/s2, of this point at full rpm? m/s2 (d) Express this radial acceleration as a multiple of g.
