At time t = 0, an anti-aircraft cannon located at (0, 0) fires a
shell at a speed 800 m/s. At the same moment, an aircraft is at
coordinate (1000, 3000) and flying in the −x direction with a
constant velocity 300 m/s. Determine at what angle(s) with respect
to the +x axis the cannon must fire so that the shell can hit the
aircraft and determine at what location the aircraft will be
hit.
