Homework Answers
The speed of earth is nearly zero, so the correct answer can't be neither chart c) nor d). The ball is thrown upward which means chart a) is also incorrect. Therefore, the correct chart is b) in which the impulse exerted by the person's arms points upward (-y direction) and so the final impulse-momentum of the ball.
