Question: (a) Two workers are trying to move a heavy crate. One pushes on the crate with a force A, which has a magnitude of 445

(a) Two workers are trying to move a heavy crate. One pushes on the crate with a force A→, which has a magnitude of 445 new tons and is directed due west. The other pushes with a force B→, which has a magnitude of 325 new tons and is directed due north. What are the magnitude and direction of the resultant force A→ + B→ applied to the crate?

(b) Suppose that the second worker applies a force B→ instead of B→. What then are the magnitude and direction of the resultant force A→- B→ applied to the crate? In both cases, express the direction relative to due west.
