A radar station locates a sinking ship at range 18.1 km and bearing 136° clockwise from north. From the same station, a rescue plane is at horizontal range 19.6 km, 154° clockwise from north, with elevation 1.90 km.
(a) Write the displacement vector from plane to ship, letting represent east, north, and up. __ km
(b) How far apart are the plane and ship? __ km
