The 222nd Field Artillery is practice firing at an old tank on the level plain below the hillside they are entrenched on. The hillside where they are located is 106 m above the valley floor. a) With a charge-five muzzle velocity of 811 m/s and the barrel elevated at 34° above the horizontal, how far will the shell go (downrange distance)? b) What will the velocity be at the instant the shell strikes the ground (magnitude and direction)?
