A jetliner is moving at a speed of 220 m/s. The vertical component of the plane's velocity is 36.0 m/s. Determine the magnitude of the horizontal component of the plane's velocity.
Use the Pythagorean theorem. The hypotenuse is 220 and the vertical component is 36.
The horizontal component must be
sqrt [(220)^2 - (36)^2]
I get 217 m/s
