ABLE MASS SYSTEM Consider at any time t a system of mass m travelling with velocity v as shown After a small time dt let its mass become m dm and velocity v dv Here a small mass dm travelling with velocity u adds into this system of mass m F is the force on r due to an external agent For the system of m dm ext v dv m dm dm U m mdi at time t I Fe du du ext I I Impulse change in momentum Fext dt m dm v dv mv dmu dua at time t dt I 1
