A radar station locates a sinking ship at range 17.5 km and bearing 136° clockwise from north. From the same station, a rescue plane is at horizontal range 19.6 km, 163° clockwise from north, with elevation 1.85 km.
(a) Write the displacement vector from plane to ship, letting i represent east, j north, and k up.
(b) How far apart are the plane and ship?
