So, if a fly travelling due south hits a car travelling due north, the fly changes direction from South to North. Therefore the fly must rapidly decellerate and then accellerate in the opposite direction. This means that the fly at one stage must be stationary and as the car is attached to the fly's bollox, the car is stationary also. Ergo, a fly can stop a car.
Ah, but as Chico finds so infuriating, we live in a relative world. One man's stationary fly is another mans squished bug whizzing along at 70mph.
we all know that a fly can stop a car, using your proof. But the same fly could stop a moped, or a container truck, depending on what it gets hit by.
The fly would stop the vehicle in exactly the same way , therefore because the mass of the vehicle varies the mass of the fly must vary upon impact.
This is also a neat proof of Einsteins theory that gf mass is dependant upon beer.
The same principle applies to something else as well, I think
