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.

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?
