Question

A 45,000 kg freighter has a momentum of 150,000 kg∙m/s towards the north. What is the magnitude and direction of its velocity?

Answer 1

Given

Mass of a freighter is m=45,000 kg

Momentum is p=150,000 kg.m/s towards north.

To find

The velocity

Step-by-step explanation

Let the velocity be v.

We know,

Momentum is

`\begin{gathered} p=mv \\ \Rightarrow150000=45000v \\ \Rightarrow v=3.33\text{ m/s} \end{gathered}`

Conclusion

The velocity is 3.33 m/s towards north.
