Centripetal acceleration = (speed)² / (radius of the curve) .
= (343 m/s)² / (0.5 km)
= (117,649 m²/s²) / (500 m)
= 235.3 m/s²
==> The acceleration of gravity is about 9.8 m/s² .
==> So 235 m/s² is about 24 'G's .
And THAT's why inexperienced passengers taking their
first ride in a military jet often pass out during a turn.
You only have to lean just a little bit into a turn at 24 G's
and the blood from your brain heads for your feet pretty quick.
