Question

a plane flies due north at 225km/h. a wind blows it due east at 55km/h. what is the magnitude and direction of the plane's resultant velocity?

Answer 1

okay, one plane is flying north, straight up and the wind blows the plane east [right]. This is almost similar to pythagorean theorem. My guess is to use x^2 + y^2 = z^2. But im pretty sure there's a formula for this in the first or two chapters of the physics book. Look there at use that formula. But in this case you have to find x which is opposite to the wind and plane.

Answer 2

it is pretty simple. to find the magnitude use the pythagorean theorem to find the resultant and then to the tangent inverse to find your angle

Answer 3

231.6km/h
