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.

Answer 1

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
