Question

A softball pitcher throws a pitch. She is facing West, and her arm starts out pointing due east with an initial velocity of 0. She is tossing an underhand slow pitch, and releases the ball 0.35 seconds into the throw when her arm is pointing 45 degrees west of north, What was her angular displacement in degrees? What was her angular displacement in radians? What was her angular velocity (in degrees / second)? What was her angular acceleration from the start of the motion to her current position (in degrees/s )?

Explanation / Answer

a) 1350
b) 2.355 rad
c) Angular accelration = 135*2/(0.352) = 2204.08 deg/sec2

angular velocity = 771.42 deg/sec

d) Angular accelration = 135*2/( 0.352) = 2204.08 deg/sec2
