In lacrosse, a ball is thrown from a net on the end of a stick by rotating the stick and forearm about the elbow.
W= 32.5 rad/s
D= 1.35 m
If the angular velocity of the ball about the elbow joint is 32.5 rad/s and the ball is 1.35 m from the elbow joint, what is the velocity of the ball in m/s?
Homework Answers
As the stick ratates about elbow, with angular velocity = w = 32.5 rad/s.
the ball will be at the circumfernce of the circular path of radius = r = 1.35 m.
then the velocity of the ball will be equal to v.
This v = wr = 32.5 x 1.35 = 43.875 m/s.

In lacrosse, a ball is thrown from a lacrosse stick by rotating the stick around the point where the player is holding it. The velocity of a ball as it leaves a stick is 30 m/s. The player’s stick is 1m long and they are holding it at its halfway point. What is the angular velocity of the head of the stick?

So lost!!!!! Help! Problem: Assume that a 1.00 kg ball is thrown solely by the action of the forearm, which rotates about the elbow joint under the action of the triceps muscle, as shown in the figure. the ball is accelerated uniformly from rest to 10.0 m/s in .350 s, at which point it is released. The distance from the elbow to the ball is 31 cm. there is 2.5 cm between triceps muscle and axis of rotation(at elbow). A)...
