A pitcher throws a baseball that reaches the catcher in 0.75 s. The ball curves because it is spinning at an average angular velocity of 230 rev/min (assumed constant) on its way to the catcher. a) Determine the angular velocity in rad/sec. b) Determine the angular displacement spend by the ball from the pitcher to the catcher.

The change in angular displacement as a function of time is the definition given for angular velocity, this is mathematically described as

Here,

= Angular displacement

t = time

The angular velocity is given as

PART A) The angular velocity in SI Units will be,

PART B) From our first equation we can rearrange to find the angular displacement then

Replacing,
