As an Engineer and Professor, I have used Physics in many applications
This question can not be answered without additional information! When the shot is fired, the boat will move in the opposite direction of the shot and reduce the initial velocity of the cannonball!. This calculation (impulse is mass time velocity) would require to know the mass of the boat!

Was the question from a book? You could "simply" ignore the reference to a boat and "assume" it wouldn't move. That then becomes a "simple" / straight-forward calculation of "projectile motion". If you need help, we can work on that, just let me know.

Assume the canon is on a flat ground, and we need to use a formula to solve this problem.

the formula is R = Vi^2 * sin(2x)/g
