At a given moment, a plane passes directly above a radar station at an altitude of 6 km and the plane's speed is 900 km/h. let theta be the angle that the line through the radar station and the plane makes with the horizontal. how fast is theta changing 12 min after the plane passes over the radar station?

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic
