We can derive a different governing equation for the missile in “Seek-Lock-Strike!“.
Looking from a different viewpoint (Fig. 1), we see
Solving (1) for ,
We also have
Equate (1) and (2) gives
The governing eqaution emerges after differentiate (4) with respect to
We let so and express (5) as
Using Omega CAS Explorer, we compute the missile’s striking time (see Fig. 3). It agrees with the result obtained previously.
Exercise-1 Obtain the missile’s trajectory from (*).
