So. Master Tigress has a pretty good feat of smashing rocks. And your boy was asked to make a go of calculating it. So away I go!
Feat is here: http://i.imgur.com/gM4F8DX.gifv
How tall is Master Tigress?[]
Unfortunatly, that's one thing we do not know. But it can be worked out.
According to the Kung Fu Panda offical website, Po is 6 foot 2, or 187.96 cm tall. And, I can use this image to find out how tall Tigress is in return.
Po is 427 pixels tall. That means that 1 pixel = 0.44 cm.
Tigress is 419 pixels tall, only barely shorter than Po. Anyway, that makes her 184.44 cm tall.
Size of the rock[]
The feat is awful for finding any size. But we do get one shot from the side, so let's go to town on that.
We know that Tigress is 184.44 cm tall. In this feat, she is 160 pixels tall, meaning that 1 pixel = 1.15 cm.
Meanwhile, the rock is 299 pixels tall, and has a base area of around 370 pixels (note. I had to make some assumptions here, as the front edge of the rock is off-screen. My assumption was based on the fact that the front end of the rock curves down smoothly to the ground.
Anyway. Thanks to those measurments, we know that the rock is 344.67 cm tall and 426.52 cm wide. As the rock is more or less a rectangular-based pyramid, all I need to do is work out the base length from the front, and we're set.
The rock is 220 pixels tall, which means that 1 pixels = 1.57 cm.
The base length of the rock is 305 pixels. Multiply one by the other, and the other base length of the rock is 477.84 cm.
The formula for the volume of a rectangular-based pyramid is:
V = (l x w x h) / 3
Plugging my numbers into that formula, I get a total volume of 2.34e+7 cm^3.
Destroying the rock[]
The rock was absolutely beat up. In the final frame, we can see small pieces flying everywhere. While there are a couple of large ones, the quantity of small pieces, and the speed at which they are sent flying everywhere. Thereby, I believe that we have Violent Fragmentation, or 69 joules per cubic centimeter.
69 x 2.34e+7 =
1,614,600,000 joules or 0.39 tons of TNT | Building level
Good supporting feat, but not much else
