weight of a hammerHeight of average japanese male = 1.72m = red line = 586 px
1px = 0.0029351535836177 m
Now I will assume the handle approximately cancels out the hole in the hammer. It seems about right, but if someone wants to have it a lot more detailed I can also calculate them seperately. (if this should be used for KE with MHS speed it would hardly matter either way)
68 px = 0.1995904436860036 m
96 px = 0.2817747440272992 m
184 px = 0.5400682593856568 m
0.1995904436860036 * 0.2817747440272992 * 0.5400682593856568 = 0.030373193814027978201697637478121157449107772416 m^3
Density granite = 2.6*10^3 kg /m^3
2.6*10^3 * 0.030373193814027978201697637478121157449107772416 = 78.9703039164727433244138574431150093676802082816 kg
Sonic flies past starsthis scene.
I will assume the glowing balls are stars and not just glowing balls or galaxys. If someone wants to disagree he can do that.
They required 6 frames to fly past the two encircled stars (note that since stars are on average 5 ly away from each other, but not necessarily in a straight line we can not count the ones in the background or at the side as well)
video runs at 30 fps.
6/30 = 0.2 seconds
5 ly = 4.730365e+16 m
4.730365e+16 / 0.2 = 2.3651825e17 m/s = 788 939 960.591 c
So about 789 million times the speed of light. (obviously MFTL+)
