Problem-1: A flywheel with a diameter of 1.20 m is rotating at an angular speed of 200 rev/min. (a) What is the angular speed of the flywheel in radians per second? (b) What is the linear speed of a point on the rim of the flywheel? (c) What constant angular acceleration (in revolutions per minute squared) will increase the wheel's angular speed to 1000 rev/min in 60.0 s? (d) How many revolutions does the wheel make during that 60.0 s?

An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 6170 rpm while it is being read, and then is allowed to come to rest over 0.368 s, what is the magnitude of the average angular acceleration of the disk?

A wheel 2 m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4 rad/s2. The wheel starts at rest at t =0, and the radius vector of point P on the rim makes an angle of 57.3o with the horizontal at this time. At t=2s, find the angular speed of the wheel

The disk starts at wo = 2 rad/s when 0 = 0, and is given an angular acceleration a = (0.30) rad/s², where is in radians.
