The projectiles had an initial velocity of v measured in meters per second at an angle above the horizon and an initial position that was h higher than where they hit the ground. How far did the projectiles move horizontally before they hit the ground? Ignore air resistance.arrow_forwardDuring the battle of Bunker Hill, Colonel William Prescott ordered the American Army to bombard the British Army camped near Boston.
