What is the resultant displacement of a car that travels 2 km north and then turns and travels 4 km east? Be sure to include magnitude and direction.
In the figure, a radar station detects an airplane approaching directly from the east. At first observation, the airplane is at distance
d₁-320 m from the station and at angle 0₁ - 44° above the horizon. The airplane is tracked through an angular change A0 - 123° in
the vertical east-west plane; its distance is then d₂ - 750 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.
