Why are sneezes so powerful?

I read that sneezes can travel up to 100 mph, why is that even necessary?

In: Biology

Its kind of a physics question.

Force = Mass * Acceleration

Therefore Acceleration = Force/Mass

Sneezes have VERY LITTLE mass, meaning it doesn’t actually take much force to get a really high acceleration.

My medical knowledge is a bit rusty by twenty years but in ELI5 terms… a sneeze uses involuntary muscles… ie you consciously don’t have control over your body sneezing once it is in the middle of a sneeze. Your body in its use, it’s trying to forcefully expel a foreign object substance, dust, dander, etc… and so your entire body is triggered, to sneeze… involuntarily and without a control mechanism.
