(choose chapter or problem)

A radar station detects an airplane approaching directly from the east. At first observation, the airplane is at distance \(d_{1}\)= 360 m from the station and at angle \(\theta_{1}=40^{\circ}\) above the horizon (Fig. 4-49). The airplane is tracked through an angular change \(\Delta \theta=123^{\circ}\) in the vertical east–west plane; its distance is then \(d_{2}\) = 790 m. Find the

(a) magnitude and

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