Physics

Two warlords aim identical catapults (i.e. they both releaserocks at the same speed) at each other, with both of them being atthe same altitude. The warlords have made the necessarycomputations to crush the other and fire their catapultssimultaneously. Amazingly, the two stones do not collide with eachother in mid-air, but instead, the stone Alexander fired passeswell below the stone that Genghis shot. Genghis is annihilated8.0s after the catapults are fired, and Alexander only gotto celebrate his victory for 4.0s before he too wasdestroyed. Find the amount of time that elapses from the launch tothe moment that the rocks pass each other in the air.
