Attempts
A soldier is tasked with measuring the muzzle velocity of a new rifle. Knowing the principles of
projectile motion, he decides to perform a simple experiment at the indoor firing range. The soldier
hangs a target a distance of d = 114 m from the end of the barrel. The rifle is mounted so that the
bullet exits moving horizontally at the same height as the bullseye. After six trials, the soldier
tabulates the values he measured for the vertical distance h from the bullseye to the bullet strike,
