    Question: if a cannonball is shrunk down to musket calibre, shot, and upon leaving the barrel grown back to cannonball size,

    A) Does mass get conserved in the shrinking?

    B) What gets conserved upon the transformation back to cannonball size?
    I) Velocity
    II) Momentum
    III) Energy

    As someone who’s inclined to take this nerd snipe, I kinda want to know.
