2) The baseball player throws a curve ball that reaches the catcher in 0.60 seconds. The ball curves because it is spinning at an average angular velocity of 330 rev/min (assumed constant) on its way to the catcher's mitt. What is the angular displacement of the baseball (in radians) as it travels from the pitcher to the catcher)

  1. ang displacement= w*time
    330* 2Pi/60sec* .6 sec=

  4. What is being calculated is the number of degrees that the ball rotates on its way to home plate. That does not tell you how much the direction of the curve ball changes. That is what I would call the angular displacement. That angle is calculable from aerodynamics (Magnus effect) and mechanics formulas, but if that isn't what they want, let it be.
