Question

wo 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.

Which best describes the movement of the boxes?

Jamal moved his box to storage, but Jude could not move his.
Jamal and Jude can successfully move each box into storage.
Jamal could not move his box to storage, but Jude could.
Neither Jamal nor Jude could move the boxes into storage.

Answer 1

Jamal moved his box to storage, but Jude could not move his.

Reason: Jamal’s upward force (60 N) exceeds the weight (50 N), so there’s a net upward force (10 N). Jude’s force (45 N) is less than the weight, so he cannot overcome gravity.
