A 3.5-inch floppy disk in a computer rotateswith a period of 2.00 * 10-1s. What are (a) the angular speed ofthe disk and (b) the linear speed of a point on the rim of the disk?(c) Does a point near the center of the disk have an angular speedthat is greater than, less than, or the same as the angular speedfound in part (a)? Explain. (Note: A 3.5-inch floppy disk is 3.5inches in diameter.)
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.

s. What are (a) the angular speed of
the disk and (b) the linear speed of a point on the rim of the disk?
(c) Does a point near the center of the disk have an angular speed
that is greater than, less than, or the same as the angular speed
found in part (a)? Explain. (Note: A 3.5-inch floppy disk is 3.5
inches in diameter.)
