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=103 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 6 trials, the soldier tabulates the values he measured for the distance, h, from the bullseye to the bullet strike. Bullet drop, h, in cm: 6.14, 7.23, 7.47, 6.27, 7.38, 6.18 What is the most accurate muzzle velocity that the soldier can report to his sergeant? What is the uncertainty in this measurement?
