thinking process … what do we need to do here...?
the flight path of the shells follow the curves of the 2 given equations.
as the shell goes up, y increases, and as the shell drops back down, y decreases.
for the 1st shell, when the shell hits the frigate, y = 0.
so we need to solve for x when y=0
for the 2nd shell, we also need to find x, when y=0.
if x equals distance of 2nd frigate, means shell will hit 2nd frigate
if x does not equal distance of 2nd frigate, means shell will not hit 2nd frigate.
