Angular+Velocity+of+a+Pitch

Data ( v = w * radius of arm) ||
 * Time (sec) || Angle (degrees) || Angle (radians) || Angular velocity (w = angle/time) || Tangental Velocity

Questions

1. What is your average tangential velocity (show work)

2. What is your velocity in Mile/hour?

3. How could you use this method to determine the velocity of a major league pitch?
