the question is:
in its approach to an airport ruway, an airplane of mass 1.24x10^5 kg has a velocity of 75.5 m/s [11.1 degrees below the horizontal] determine the horizontal and vertical components of its momentum

Find the horizontal and vertical components of its velocity. (Hint: one is v*sin(ø) and the other is v*cos(ø).) Each velocity times the ariplane's mass is that direction's component of momentum.

Use trigonometry.
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Hypotenuse = scalar momentum
Opposite = vertical component
Adjacent = horizontal component
The angle is given. Just multiply the trig function results by the scalar momentum and voila!
