A jetliner is moving at a speed of 305 m/s. The vertical component of the plane's velocity is 47.5 m/s. Determine the magnitude of the horizontal component of the plane's velocity.
Think: Pythagorean theorem. Horizontal and Vertical velocity components and speed (magnitude) form a right triangle.
sqrt[(305)^2 - (47.5)^2] will give you the answer
