How to rotate a Direction Arrow to a particular location?

A ball moves in the direction of the arrow labeled e in the figure. Momentum question?

  • A ball moves in the direction of the arrow labeled e in the figure. The ball is struck by a stick which briefly exerts a force on the ball in the direction of the arrow labeled g in the figure. Which arrow best describes the direction of ΔP, the change in the ball's momentum? e is downwards, and g is to the left. The figure has a-h, going clockwise starting with a pointing upward. Thank you!

  • Answer:

    The answer is g. Change in the ball's momentum coincides with force direction.
