Question

Imagine you are standing on a skateboard, initially motionless. You throw a medicine ball horizontally while on the skateboard and as a result you roll backward.

1. Model this situation by creating a complete momentum chart with the initial momentum at a time just before you throw the ball and the final momentum at a time just after letting go.

2. Consider the same scenario but use an interval with the final state chosen after the motion of the throw, but before the ball left your hands: Would you roll backward, forward, or remain in the same spot at that moment? Create a complete momentum chart to argue your case, and write out the reasoning for your answer.
