## Homework Statement

A jetliner takes off from LA. after 5 min, the jet has an altitude of 5 km above the level of the airport and is 25 km west and 10 km north of the airport. What are the magnitude and the diretion of its displacement during this time interval? Specify the direction by stating two angles: the angle of the displacements direction west of north and the angle of the displacement's direction above the horizontal.

## Homework Equations

for West of North:

construct a triangle with adjacent side 10 km and hypotenuse 25 km

then use cox=10/25 to find the angle

For above the horizontal:

construct a triangle with opposite side 5 km and hypotenuse 10

then use tanx=5/10 to find angle

For magnitude:

use the magnitude formula for: [-25 km, 10 km, 5 km]

## The Attempt at a Solution

Is horizontal always the Z component/up?

west of north angle: 66*

above horizontal angle: 27*

direction of displacement: northwest

magnitude: 27 km
