what would be the best equation to find momentum?

Probably Use

\vec p = m \vec v
Or

\vec F =\frac{d\vec p }{dt}

The momentum of what? Given what? The definition of momentum of a particle is

\mathbf{p} = m\mathbf{v}

Once you know the mass and the velocity you know the momentum.

Momentum is measured in kilogram*meters/second (kg*m/s)

E^2 - (pc)^2 - p^2c^4 = 0
