Problem 2. a) A rifle fires a 5.56x45 NATO bullet horizontally with muzzle velocity of 950 m/s, while a modern crossbow fires a bolt horizontally with initial velocity of 67 m/sec. Assuming no air resistance, what is the drop distance at 50m, 100m, 200m, 300m, 400m? How realistic are these estimates?

Please help me solve this problem

Problem 2.
a) A rifle fires a 5.56x45 NATO bullet horizontally with muzzle velocity of 950 m/s, while a modern
crossbow fires a bolt horizontally with initial velocity of 67 m/sec. Assuming no air resistance, what
is the drop distance at 50m, 100m, 200m, 300m, 400m? How realistic are these estimates?
b) A longbowman launches arrows at 50 m/s. What is the gained improvement in maximal range to
ground targets when he fires from the skirt wall (height=10m), secondary wall (height=20m), and
keep (height=30m) of a medieval castle? What if the castle is built on a hill of height 100m?
