Question

In lacrosse, a ball is thrown from a net on the end of a stick by rotating the stick and forearm about the elbow. If the angular velocity of the ball about the elbow joint is 35.0 rad/s and the ball is 1.50 m from the elbow joint, what is the velocity of the ball?
m/s

m/s



Explanation / Answer

Linear velocity =angular velocity x radius

v =w r = 35 x 1.50 =52.5 m/s
