Question

Determine the magnitude and the direction of the momentum of a 1200 kg truck traveling at 20 m/s towards the east.

Answer 1

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

$\begin{gathered} p=mv \\ \Rightarrow p=1200\times20 \\ \Rightarrow p=24000\text{ kgm/s} \end{gathered}$

towards east

Conclusion

The momentum is 24000 kgm/s towards east
