A spying helicopter is flying due west over level ground at a constant altitude H and at a constant speed V.
A solider on guard, who is due west of the helicopter, saw the helicopter twice and roughly measured the
angle between the ground and the helicopter. The first measurement the solider got is $\theta_1$ degrees and the
second measurement, which he made t seconds later, is $\theta_2$ degrees. Suppose the helicopter has not yet
passed over the soldier as shown. Synthesize a well-formed solution which delineates how fast the
helicopter is travelling west in meters per second. A well-formed solution should be derived step by step in a
logical sequence, and it should be generic and symbolic. Once this is completed, test your solution with the
values H = 222m, $\theta_1$ = 6°, $\theta_2$ = 75°, t = 30s.
REMEMBER - Do more than just calculate a numerical answer. Prepare a solution which can be easily
followed by your colleagues and forms the foundation for a generic symbolic relationship which can be
communicated to the computer. You do NOT need to implement your solution with a MATLAB script,
but you should test your solution with the above sample values manually.
