A field hockey player's arm and stick form a rigid segment. Assuming she hits the ball when the stick is vertical, which of the following would result in the greatest velocity of the end of her stick immediately before she hits the ball?
a) She stands still and swings her arm/stick at 300 deg/s
b) She runs forward at 4 m/s and swings her arm/stick at 300 deg/s
c)She stands still and swings her arm/stick at 150 deg/s
d) She runs forward at 2 m/s and swings her arm/stick at 150 deg/s
If you could explain why you chose your answer as well. Thanks :)
