Textbook Question
Chapter 11, Problem 15P
A tracking radar antenna is locked on an airplane flying at a constant altitude of 5 km. and a constant speed of 540 km/h. The airplane travels along a path that passes exactly above the radar station. The radar starts the tracking when the airplane is 100 km away.
(a) Derive an expression for the angle ? of the radar antenna as a
(b) Derive an expression for the angular velocity of the antenna, dθdt , as a function of time.
(C) Make two plots on the same page, one of ? versus time and the other of dθdt versus time, where the angle is in degrees and the time is in minutes for 0≤t≤20 mm.
