So kinetic energy of the bullet: one half of m (mass) times v (speed) squared...

v squared is 3000 km/h squared and that is 9,000,000 and actually all this should be calculated in meters and seconds...

Which is relevant momemtum or kinetic energy ?

Momentum is simply velocity x mass ... and the ratio is adimensional ... that's my last post on the subject, I don't want to attract here the UBI forum's masters of physics ...
