User blog:Uninown/Dreamverse: A mecha falls from a skyscraper (not quite)

I'm going to do this simple feat for record's sake.

To provide context, a 'mecha' trips from a high-rise platform serving as a battleground for all the chaos going around; a tournament. The machine sacrifices itself and slamming the opponent into pieces as he hit the ground but inevitably gets disqualified, though he goes mostly unscathed. We'll calculate that today.

I'm assuming the use of the equation GPE = mgh.

m is the mass of our falling object, in this case the giant bot. This is a bit tricky, since it's only described as being heavy as a "large building". I'll be using that of a skyscraper, or 250,000 tons (250,000,000 kilograms)

g equals to the planet's gravity, in this case Earth's, which is 9.81 m/s^2.

h is equal to the height the object was falling till it hit the ground; this is unfortunately kind of vague, merely described as "extremely high" and "sky-scraping". It may, indeed, be a bit wank, but what'll be used here will be 1 mile (or 1609 meters rounded up). 20 meter robots couldn't even see the ground, after all.

Having all these values done, we're ready to put things together.

GPE = 250,000,000*9.81*1609 = (3946072500000 J)/4.184 =

(943133962715.105)/10^9 = 943.133962715 tons, or very high-end Multi-City Block level+.

This'll scale to durability and consequently to AP, I guess.
