Question

What is the velocity of an object that has a mass of 2.5 kg and a momentum of 1,000 kg · m/s?

Answer 1

The object's speed is (1000 kg-m/s) / (2.5 kg) = 400 m/s.

We can't describe its velocity because we don't know what direction it's moving.

Answer 2

Using the momentum formula p=mv, it can be determined that v=p/m. Therefore 1000/2.5 = 400. The object is going 400m/s
