Units in (1): $ \dfrac{\text{kg}}{m^3} \times m^3 \times ms^{-1} = kgms^{-1}$

Units in (2): $ \dfrac{kgms^{-1}}{s}=kgms^{-2}$

Units in (3): $ \dfrac{kgms^{-2}}{m^2} \times m^2 = kgms^{-2}$

Units in (4): $kgms^{-2}$

So the answer is: $ \dfrac{\text{kg}}{m^3} \times m^3 \times ms^{-1} = kgms^{-1}$
