A jetliner is moving at a speed of 235 m/s. The vertical component of the plane's velocity is 34.3 m/s. Determine the magnitude of the horizontal component of the plane's velocity.
_____________m/s

Vo = 235m/s @ A-deg.

Yo = ver. = 34.3m/s.

sinA = Yo / r = 34.3 / 235 = 0.14595,
A = 8.393.

Xo = hor. = r*cosA = 235*cos8.393 = 232.5m/s.
