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 35.0 m/s and the ball is 0.300 m from the elbow joint, what is the angular velocity of the forearm?

Group of answer choices

10.5 rad/s

0.0952 rad/s

0.00857 rad/s

117 rad/s

Step 1

Given:

Velocity of the ball in pitcher’s hand = 35.0 m/s

Distance between the ball and the elbow joint = 0.300 m

This distance act as the radius for the circular track followed by the pitcher hand before pitching

Step 2

Relation between angular velocity and the linear velocity is given by,

Step 3

Before pitching, the ball is in the hand of baseball pitcher.

Therefore, ang...
