When the mass varies due to accretion or ablation, [an alternate equation explicitly accounting for the changing mass] should be used."↑ Halliday. Physics. Vol. 1. p. 199. ISBN 0471037109. It is important to note that we cannot derive a general expression for Newton's second law for variable mass systems by treating the mass in F = dP/dt = d(Mv) as a variable. [...] We can use F = dP/dt to analyze variable mass systems only if we apply it to an entire system of constant mass having parts among which there is an interchange of m
