During the battle of Bunker Hill, Colonel William Prescott ordered the American Army to bombard the British Army camped near Boston. The projectiles had an initial velocity of 43 m/s at 33° above the horizon and an initial position that was 36 m higher than where they hit the ground. How far did the projectiles move horizontally before they hit the ground? Ignore air resistance.
