What is the final angular position of an object if it has an initial angular position of -19.49 rad relative to some zero position, an angular acceleration of 1.2 rad/s/s, an initial angular velocity of 9 rad/s, and it rotates for a time of 3.24s?

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
