Two boxes need to be moved into storage. Jamal and Jude each want to move a box. The force of gravity on both the boxes is 50 N. Jamal is lifting with a force of 60 N, and Jude is lifting with a force of 45 N.

To lift a box, the upward force must be greater than its 50 N force of gravity. Jamal lifts with 60 N, so he can lift his box; Jude lifts with only 45 N, so he cannot. Therefore, Jamal moved his box to storage, but Jude could not move his.
