Abaseball 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 37.137.1 m/s (about 8383 mph) and the ball is 0.3300.330 m from the elbow joint, what is the angular velocity of the forearm?

112.4 rad/s

Explanation:

= velocity of the ball in the pitcher's hand = 37.1 m/s

= distance of ball from the elbow joint = 0.330 m

= angular velocity of the forearm

Angular velocity of the forearm is given as

Inserting the values

= 112.4 rad/s

The length of the simple pendulum is 0.248 m.

Explanation:

Given;

period of the simple pendulum, T = 1.00 s

let the length of the simple pendulum = L

The period of oscillation of a simple pendulum is calculated as;

Therefore, the length of the simple pendulum is 0.248 m.
