So let's say for example I have an object with 5kg of mass.
It explodes with a force of 500N.
The object fragments into four fragments: a 0.5kg, a 1kg, a 1.5kg and a 2kg object.
What force does each of those fragments have (and thus what acceleration)?
My assumption is that it will get a percentage of the force relative to the percentage of the mass. So the 1kg fragment is 1/5th of the original mass thus it gets 1/5th of the force?
