Knowing the Table 1: Vertical principles of projectile motion, he decides to perform a simple experiment at the displacement data firing The soldier hangs d- from the end of the barrel. The rifle is mounted so that the bullet exits moving horizontally at Bullet drop, the same height as the bullseye. After 6 trials, the soldier tabulates the values he h, in cm measured for the distance, h, from the bullseye to the bullet strike. 6.03 7.23 7.47 7.38 6.29 What is the most accurate muzzle velocity that the soldier can report to his sergeant?

Explanation / Answer

suppose bullet goes h distance downward.

then using d = uy*t + ay*t^2 /2 in vertical

- h = 0 - gt^2 /2

t = sqrt(2h/g)

in horizontal,

d = v0t

v0 = d/t = d / sqrt(2h/g)

avergae value of h = (6.03 + 7.23 + 7.47 + 5.94 + 7.38 + 6.29) / 6

h = 6.72 cm = 0.0672 m

v0 = 101 / sqrt(2x0.0672 / 9.8) = 862.68 m/s
