39. We adopt the positive direction choices used in the textbook so that equations such as
Eq. 422 are directly applicable. The coordinate origin is at the end of the rifle (the initial
point for the bullet as it begins projectile motion in the sense of § 45), and we let
θ
0
be
the firing angle. If the target is a distance
d
away, then its coordinates are
x
=
d, y
= 0.
The projectile motion equations lead to
