a baseball pitcher brings his arm forward during a pitch, rotating the forearm about the elbow. if the velocity of the ball in the pitcher's hand is 34.534.5 m/s (about 7777 mph) and the ball is 0.2900.290 m from the elbow joint, what is the angular velocity of the forearm?

119.06 rad/s is the angular velocity of the forearm.

ball velocity, v = 34.53 m/s

Distance from elbow joint ; r = 0.29 m

[tex]Angular velocity=velocity/distance=v/r[/tex]

[tex]Angular velocity =34.53/0.290=119.06rad/s[/tex]

Angular velocity is the speed at which the angle between two bodies changes as an item rotates or revolves around an axis.

Angles or angular displacements are frequently described in technical terms such as degrees, revolutions (of 360°), and revolutions per minute (rpm). Angles and angular velocities are often given in radians and radians per second, respectively, in mathematics and physics. These conversion factors link these measurements together: A radian equals 1/180 (or 0.0175) of a degree, and a radian per second = 1/30 (or 0.105) of a radian.
