The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 4 kg
velocity = 84 m/s
We have
momentum = 4 × 84
We have the final answer as
<h3>336 kgm/s</h3>
Hope this helps you

The concept of a black hole seem reasonable to me because of its valid and authentic evidences.
<h3>What are the causes, characteristics, and major features of black holes?</h3>
