A solid flat disk is rotating in the counter-clockwise (or positive) direction. There is an object (small black dot) on the disk, rotating with the disk. The object is a distance 1.20 meters from the axis of rotation (the center of the disk). It had an angular velocity of 3.50 radians / second at the initial position of 0 Radians (see black line on image). After 1.53 seconds, it has an angular velocity of 7.50 radians / second at the position shown in the picture.

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.

A solid flat disk is rotating in the counter-clockwise (or positive) direction. There is
an object (small black dot) on the disk, rotating with the disk.
The object is a distance 1.20 meters from the axis of rotation (the center of the
disk). It had an angular velocity of 3.50 radians / second at the initial position of 0
Radians (see black line on image). After 1.53 seconds, it has an angular velocity of
7.50 radians / second at the position shown in the picture.
O Radians
What is the angular acceleration as it has moved from the 0 position to the current
position?
