    Probably Use

    [tex]\vec p = m \vec v[/tex]
    Or

    [tex] \vec F =\frac{d\vec p }{dt} [/tex]

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

    [tex]\mathbf{p} = m\mathbf{v}[/tex]

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

    What are the units momentum is measured in?

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

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