Question

A strong wind blows to the west at a speed of 38.7 mi/h relative to the ground causing a commercial plane to change course What should be the plane's velocity in order to maintain a southward direction at a constant speed of 452 mi/h relative to the ground?

2. Problem Solving
A. A motorboat is crossing a river that flows
eastward at a speed of 5 km/h. If the boat needs
to maintain its northward course and a speed of
10 km/h relative to an observer standing on the
riverbank, what should be its velocity relative to
the river. (Hint: Solve for Vu)
B. A strong wind blows to the west at a speed of 38.7 mi/h
relative to the ground causing a commercial plane to change
course. What should be the plane's velocity in arder to
maintain a southward direction at a constant speed of 452
mi/h relative to the ground?
