A flywheel turns through 38 rev as it slows from an angular speed of 4.1 rad/s to a stop. (a) Assuming a constant angular acceleration, find the time for it to come to rest. (b) What is its angular acceleration? (c) How much time is required for it to complete the first 19 of the 38 revolutions? (a) Number Mi (b) Number i (c) Number Ma Units Units Units >

A rotating wheel requires 8.00 s to rotate 29.0 revolutions. Its angular velocity at the end of the 8.00-s interval is 97.0 rad/s. What is the constant angular acceleration (in rad/s) of the wheel? 5.67 This is the angular acceleration to start from rest and to rotate the given number of revolutions in the given time. The wheel will not have the required final angular velocity in this case. rad/s Need Help? Read It Master It O Show My Work (Optional)

At time t = 0 s, a wheel is spinning at 84 rad/s counterclockwise.  It begins accelerating counterclockwise at 11 rad/s2 until its angular speed is doubled, then the angular acceleration is reversed until the wheel comes to a stop.  How many times does the wheel spin (measured in number of rotations) between t = 0 and when the wheel comes to rest? (Please answer to the fourth decimal place - i.e 14.3225)

An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 2250 rpm while it is being read, and then is allowed to come to rest over 0.301 s, what is the magnitude of the average angular acceleration of the disk? angular acceleration: 782.79 rad/s? If the disk is 12.0 cm in diameter, what is the magnitude of the tangential linear acceleration of a point 1/11 of the way out from the center of the disk? linear acceleration: m/s?
