In the figure, a radar station detects an airplane
approaching directly from the east. At first
observation, the airplane is at distance d₁ = 390 m
from the station and at angle 0₁ = 45° above the
horizon. The airplane is tracked through an
angular change A0 = 120° in the vertical east-west
plane; its distance is then d₂ = 760 m. Find the (a)
magnitude and (b) direction of the airplane's
displacement during this period. Give the direction
as an angle relative to due west, with a positive
angle being above the horizon and a negative angle
being below the horizon.

Expert Solution
Step 1

Given:

At first, the distance between the station and the airplane is, d1=390 m.

At first, the angle between the station and the airplane above the horizon is, θ1=45.

The angular change of the airplane is, θ=120.

The distance between the station and the airplane after the angular change is, d2=760 m.

To compute:

(a) the magnitude of the airplane's displacement during this period.

(b) the direction of the airplane's displacement during this period.
