a small plane heads west at 320 kph. there is a north wind blowing at 24 kph. what is the velocity (2 parts!) of the plane with respect to the ground?

would the answer be 320.9 kph? but there are two parts to the answer. what is the other part?

3 answers

velocity has two components,
1. magnitude, your answer is correct for that
2. direction
look at your triangle, it was clearly right-angled, and you found the length of the hypotenuse
Now, can you find one of the acute angles ?
(hint: tangent)
would it be approximately 4.29°?
Yes, make sure your wording of the answer matches your diagram.

I don't know which method you use to state direction angles, but it could be called
W 5.29° S
