Given
Mass of the truck, m=1200 kg
The velocity is v=20 m/s
To find
The magnitude and direction of the momentum
Explanation
The momentum is given by
[tex]\begin{gathered} p=mv \\ \Rightarrow p=1200\times20 \\ \Rightarrow p=24000\text{ kgm/s} \end{gathered}[/tex]towards east
Conclusion
The momentum is 24000 kgm/s towards east
