Assume you are a Medieval knight attacking a castle with a cannon. The ball leaves the cannon with a speed of $38\mathrm{.}7$ m$/$s$.$ The barrel's angle with respect to the ground is $40\mathrm{.}5$o$,$ and you make a perfect hit on the tyrant's chamber which is at the same level as the cannon's muzzle. What is the time of flight of the cannon ball?
