7. Two workers must pick up bricks that lie on the ground and place them on a worktable. They each
pick up the same number of bricks and put them on the same height worktable. They lift the bricks so
that the bricks travel upward at a constant velocity. The first gets the job done in one-half the time that
the second takes. Did one of the workers do more work than the other? If so, which one? Did one of
the workers exert more power than the other? If so, which one?
