User blog:Zanybrainy2000/Be a wall!: Speed and kinetic energy of the wall

In this random satiric Roblox game I found, you can play as a wall that is a portion of the size of the U.S out of sheer size, as shown in this picture below:



The size of the wall made me wonder how much kinetic energy it can generate via running, as it can easily run (Horizontally; assuming the 'tip' of it is where it ends) across the U.S in under a minute, as shown below:



Before I can use this speed in a KE formula, I need to calculate its weight:



Blue line (Length of U.S): 1706 pixels.

Cyan line (Wall length): 58 pixels

The horizontal width of the U.S is 2680 miles.

2680/1706 = 1.57092614 miles per pixel.

This is the pixel/length ratio I will use for calculating the dimensions of the wall.

The wall is 58 pixels long:

1.57092614 x 58 = 91.1137161 miles long

I changed the camera angle (But I did not zoom in), so the pixel/length ratio should be identical:



Cyan line (Going from bottom of head to bottom of the wall): 42 pixels

42 x 1.57092614 = 65.9788979 miles tall

I did the same thing to find the width of the wall:



Cyan line (Width): 14 pixels.

14 x 1.57092614 = 21.992966 miles wide.

All I need to do next is multiply these values by each other to obtain the volume.

21.992966 x 65.9788979 x 91.1137161 = 132212.531109 cubic miles, or 551085869264031.1 cubic meters

The density of common red bricks is usually 1,922 kilograms/m^3

1,922 x 551085869264031.1 = 1.059187e+18 kilograms

The only thing we need to do left is to find the speed of the wall (Which is shown in the video above)

The wall starts running at 0:01 and reaches the end of the U.S at 0:23 - which means it took 22 seconds for the wall to run from one end of the U.S to the other.

The horizontal width of the United States is 2,860 miles (4602723.84 meters).

4602723.84 / 22 = 209214.72 m/s (Mach 609.955451895).

Massively Hypersonic

Now that a speed value has been calculated for it, we can apply this to its kinetic energy:

1.059187e+18 x 0.5 x 209214.72^2 = 2.31807307e28 joules (5.54032760516 Exatons of TNT)
