1. The problem statement, all variables and given/known data This is a conceptual question: A ball is thrown to a person (at rest) on a skateboard. Should the person catch or deflect the ball to achieve the greatest velocity. 2. Relevant equations 3. The attempt at a solution I thought it would be catching the ball, catching the ball means the force acting on the person for a longer duration of time and therefore larger impulse and larger change in momementum which means larger final velocity. Thanks!
