The muzzle speed for a Lee–Enfield rifle is 630 m s−1 . Suppose you fire this rifle at a target 700 m away and at the same level as the rifle. (a) In order to hit the target, you must aim at the barrel at a point above the target. How many meters above the target must you aim? Pretend there is no air resistance. (b) What will be the maximum height that the bullet reaches along its trajectory? (c) How long does the bullet take to reach the target?
