Using
a simple pendulum experiment similar to the one done in Physics 211
lab, the ISB Journal of Physics was able to

find the relationship between the velocity of a paintball to the distance travelled. By changing distances between the fired range and using a combination of video analyzing software, and were able to calculate the maximum velocity of the paintball by
measuring the distance of horizontal motion of the pendulum. Throughout this experiment, there was an inverse relationship between velocity and distance. The farther the distance, the lower the velocity of the paintball travelling through the air.
After estimating and calculating the drag coefficient, the average muzzle velocity was then found in the experiment.
It should be known that through this experiment the force due to gravity was neglected because it was only analyzed in the horizontal motion. Vertical displacement since it was related to the horizontal distance, was calculated from the horizontal displacement.
