# Which has more momentum, an object with a mass of 3kg moving at 14m/s or an object with a mass of 12kg moving at 6m/s?

Know that $p = m v$, where p is momentum, v is velocity, and m is mass. Since all the values are in SI units already, there is no need for conversion, and this becomes just a simple problem of multiplication.
1.$p = \left(3\right) \left(14\right) = 42 k g \cdot \frac{m}{s}$
2.$p = \left(12\right) \left(6\right) = 72 k g \cdot \frac{m}{s}$
