It may be interesting to others if we stay pigheaded and post it all right here! Ha! OK, let's say vertical plane, no air, only gravity. The amount of force in ft/lbs. on exit from the barrel is say >1300 ft/lbs. (no energy expended to clear the air from the barrel), velocity of the round goes to something in the neighborhood of 3000 mph at the barrel, and the max altitude of the round goes to about 11,000 feet in a vacuum, lifting a 55 gram round, working only against earth gravity. From 11,000 ft to 0 feet at 32 ft/sec/sec (the formula is correct) and weight is irrelevant in falling - (but it is relevant in knowing how far up the round can fly given the power of the explosion). I eyeball it at a about 600 mph when it hits the ground. So the answer to the science teacher is you're wrong, we were going faster when we left the tube than when we hit the ground. Run the numbers and let me know if you come up with something markedly different, or see some flaw in my assumptions.
