For a rocket in free space, it seems that(adsbygoogle = window.adsbygoogle || []).push({});

[tex] P = mv + (m_0 - m)(v-u) [/tex]

where m is the mass of the rocket, v is its speed, m_0 is its initial mass, u is the speed of the propellent relative to the ship.

But in solving dP/dt=0, I get that the velocity is linear in m. There seems to be a mistake in what I have taken to be the total momentum. Can anyone point it out?
