a tennis serve, a racket is given an angular acceleration of magnitude 87.64 rad/s/s. At the top of the serve, the racket has an angular speed of 18.71 rad/s. If the distance between the shoulder and the top of the racket is 1.1 m, find the magnitude of the total acceleration of the top of the racket

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 .
