# How much momentum does a 2 kg object moving at 4 m/s have?

The equation of momentum is basically $p = m v$ where $p$ is the momentum of the object, $m$ is the given mass of the object and $v$ is the velocity of the object.
So in the above question, $v = 4 m {s}^{-} 1$, $m = 2 k g$, so that means momentum is $p = m v = 2 \cdot 4 = 8 k g m {s}^{-} 1$
