Hmmm, isn't that how we get the apparent speed of the object?Something that came up to me: If a person began moving while everything was completely still with no movement in the person’s perspective for what seemed to be seconds or even minutes, if it took what seemed to be seconds or even minutes for the time-frozen people/objects to move a single pixel in the faster person’s perspective, would that be possible to divide the time of how long it took the time-frozen people to move a single pixel?
Lemme make an example.
Suppose the bullet is frozen in view. It is available as frozen for 5 seconds before everything returns to normal. Suppose the 9mm bullet is 50px and 1px is 0.18 mm or 0.00018 m (The distance it moved in that timeframe). 9mm rounds out of a Beretta go at 381 m/s.
Thus, apparent speed: (0.00018/5)= 0.000036 m/s
Now, let's just say person is running at normal running speeds in their view, 6 m/s
Slow-mo formula: (True speed of projectile / apparent speed of projectile) * Person's apparent speed
Person's true speed: (381/0.000036) * 6= 63,500,000 m/s or 0.2118 c (21.18% SoL)
