1 During a physics lab, Jack and Jill ran up a hill. each carrying boxes of candy which weighs 10 Newtons. Jill runs the same distance up the hill as Jack but in half the time. (Explain your answers)T a. Who does more work? It's jack, because he weighs more and has to use move powers to move. b. Who delivered the most power and why? Jill has more power because of how he is going.
