Answer 1

1. Both Jack and Jill did the same amount of work. 2. Jill delivered the most power.

Answer 2

1. Work is defined as the force applied on an object times the distance it moves. In this case, both Jack and Jill are moving the same distance up the hill, so they both do the same amount of work, regardless of their masses.2. Power is defined as the rate at which work is done. Since Jill ascended the same distance in half the time as Jack, she did the same amount of work in a shorter amount of time. Therefore, Jill delivered the most power.
