Question

background info: this is a 2D air puck collision lab where we collide 2 metal pucks together (each puck has a spark timer under it) and we calculate the momentum and energy of each puck before and after collision

I am doing error analysis for the lab, and I am questioning if sound produced when 2 metal pucks hit each other is a major error or a minor error towards energy loss

this is total energy before: 0.041256281J
and this is total energy after: 0.034575303J

and the percentage of energy lost was 16.2%

would the sound produced during collision carry energy (J) large enough to contribute to the percentage difference in a major way or minor way? what would be the approximate amount of energy lost to the sound of two metal pucks colliding with each other?
