There are many issues with our calcs of this feat, such as using the radius of Manhattan instead of the diameter or calculating the speed with ang sizing, a very unreliable way to find distance. Therefore, I’ve decided to redo this calc from the ground up to get a truly accurate result.
Using Google Maps distance measuring tool, the rock is 21.08 kilometers or 21080 meters and 310.220889045 pixels long.
The rock has a height of 127.19276709 pixels or 8642.9496689 meters.
Dividing 21080 meters by 2 gives us a radius of 10540 meters.
Volume of a cone = (pi × r2 × h)/3
Volume of rock = 1,005,476,266,067.736 m^3
Density of continental crust, stone and earth = 2700 kg/m^3
Mass of rock = 2,714,785,918,382,887.2 kilograms
To get the distance the rock travelled, I first measured the motion line at the beginning and end of its route.
The end of the line is 99 pixels or 6727.20656054 meters.
The beginning of the line is 21 pixels or 6727.20656054 meters.
I made a line with same distance on Google Earth using Coney Island, appropriately enough, and zoomed out and measured the pixels of the line at various distances to get the same results.
At 300 kilometers the line is 99 pixels long.
At 1,000 kilometers the line is 21 pixels long.
1,000-300 = 700 kilometers.
Let's do what Asura did and assume the rock moved the distance in 5 seconds.
700 kilometers/5 seconds = 140,000 m/s
