You're just going to have to accept that the physics don't make sense.

When she hits mach 1, she leaves behind a trail of rainbow, which flies in the face of everything we know about quantum electrodynamics (and rainbow formation). Ignoring the implications of that on Planck's constant and the speed of light, the rainbow hangs in the air for an extended period of time, which is completely absurd.

@Jake: Assuming g=9.8, mach 1 could be acheived by falling for about 34 seconds. Dash accomplishes it in 20 seconds, so since she isn't flapping, she had to have an initial velocity of 137 m/s, or 306 miles per hour. Therefore, she would have needed to fall from a height of 4.7km.

Aside from being able to go 306mph almost instantly, most of that is fairly reasonable. But we don't really get a clock on the speed of pegassi very often, maybe that's normal. Predatory birds have been known to go 100mph.

All that aside, we do know that pegassi have passive magic which allows them to walk on clouds. If mass bends to your will such that you can stand on water vapor (must be millions of orders of magnitude different from reality)... I'm sure that a few thousand g's is easy for a talented pegasus to dissipate. (Somethin's wrong with my g-diffuser!)
