Sagot :

Given data

*The given mass of the rocket is m = 14000 kg

*The given momentum is p = 2.8 × 10^7 kg.m/s

The formula for the velocity of the rocket is given by the momentum formula as

[tex]\begin{gathered} p=mv \\ v=\frac{p}{m} \end{gathered}[/tex]

Substitute the known values in the above expression as

[tex]\begin{gathered} v=\frac{2.8\times10^7}{14000} \\ v=2000\text{ m/s} \end{gathered}[/tex]

Hence, the velocity of the rocket is v = 2000 m/s
