Question

What is the momentum of a 139 kg motorcycle

that is moving at 23 m/sec towards the North?

Answer 1

The momentum of a 139 kg motorcycle that is moving at 23 m/sec towards the North can be found with a simple equation:

$$\vec{p}=m\vec{v}=139·23=3197\text{ kg-m/s}.$$

Direction is the same as velocity, that is, Northward.
