If you drop a unit cannonball from a height of 16 feet, how fast will it
hit a nail in a wood block target on the ground?

How could you measure this?

Suggestion: Doppler radar.

Suppose we agree with the penetration of the nail in the wood block
being 1 inch.

If you now drop a unit cannonball from a height of 32 ft, how fast will
it hit the nail?

Will the penetration of the (new) nail be 1 inch, 2 inches or 4 inches?

Why?

If ypu now drop a cannonball of mass 2 from a height 16 ft, what will be
the penetration of the nail?

These are the sort of experiments that people conducted nearly 400 years
ago,
they were interested in how to knock over walls with cannonballs.

How much energy was simply how much gunpowder, because gunpowder had to
be paid for. So does more up-to-date munitions and aircraft fuel. Why
carry a heavy load
up to 30,000 ft and halfway around the world if you only going to put
down again, when you could have refueled? That airline would not stay in
business long if it didn't have just enough fuel to make each trip,
flying people is a competitive business. Why do you think they weigh
your bags? Not enough fuel and you ditch in the ocean, too much and you
waste money. if the equations were wrong, a lot of people would have
noticed.
