hi guys!~ i was going through my test papers and found a question that i don't understand >_<
when a rocket is shot upwards and at the point where it stops in the air, it explodes...
so why does its momentum remain unchanged but the kinetic energy is increased??
~by the way, the answer that i came up wif was that its momentum and kinetic energy increases, because the formula for momentum and kinetic energy both has mass and velocity in it, so what i tot was that both would have to increase together or remain unchanged together ==''
