Ok. I checked it myself. Rhe problem is we don't see the moment it hits the ground. So 2 different assumptions
We see the moment it's fired and it's already off screen
1 Frame
24 Frames in a second and the earth is 92,955,807 miles away
92,955,807 * 24 = 2,230,939,368 MPS Or 8031381724800.001. MPH
11976.114776892060036 cc
And then using the time to took for the camera to go down and show it's at earth
20 Frames
24 Frames in a second and the earth is 92,955,807 miles away
92,955,807 divided by 20 = 4,647,790.35 Miles per frame
4,647,790.35 * 24 = 111,546,968.4 MPS or 401569086240.0001 MPH
598.80573884460306999 CC
There's that.
