#rho=summv#

#∫Fdt=Δρ+C#
#ρ=J+ρ_("initial")#

#J=∫_0^tFdt#

Explanation:

All of the masses and all of their respective velocities multiplied and take the sum of all of those.

In terms of units:
#∫Fdt=kg*m/s^2*s=(kg*m/s)# this is momentum

#J, "impulse"=∫_0^tFdt#, because this is solely the change in momentum rather than the final.
