## Homework Statement

Suppose you have a projectile of 120g.

Suppose that projectile is accelerating at 9186.05 m/s/s for 0.129 seconds, to a velocity of 12150 m/s.

Factoring in a 20% drop in Velocity from aerodynamics and friction, it accelerates to roughly 9750 m/s.

What distance did the projectile travel in the 0.129 seconds that it was accelerating? Please provide relevant units of measurement.

## Homework Equations

d=vt+1/2at

^{2}

## The Attempt at a Solution

I plugged everything into the above equation, but I don't feel like it is a realistic value, and I'm not sure of what unit is used (m, km, cm, etc...)
