# Which has more momentum, an object with a mass of 5kg moving at 15m/s or an object with a mass of 16kg moving at 7m/s?

See below.

#### Explanation:

Momentum is given as:

$p = m v$

Where:

$\boldsymbol{p}$ is momentum, $\boldsymbol{m}$ is mass in kg and $\boldsymbol{v}$ is velocity in $m {s}^{-} 1$

So we have:

$p = 5 k g \times \frac{15 m}{s} = \frac{75 k g m}{s} = 75 k g m {s}^{- 1}$

$p = 16 k g \times \frac{7 m}{s} = \frac{112 k g m}{s} = 112 k g m {s}^{- 1}$
