# How much momentum does a 1/4 kg object moving at 32 m/s have?

Apr 30, 2018

See explanation.

#### Explanation:

Momentum is calculated as a vector with value equal to product of velocity ($v$) and mass ($m$) and direction equal to the direction of velocity vector.

## $\vec{p} = m \cdot \vec{v}$

Here the value is:

## $p = \frac{1}{4} \cdot 32 = 8 \left[k g \cdot \frac{m}{s}\right]$

$8 \setminus \text{kg m/s}$

#### Explanation:

Momentum of an object is given by the equation:

$p = m v$

• $m$ is the mass of the object

• $v$ is the velocity of the object

So, plugging in our given values into the equation, we get:

$p = \frac{1}{4} \setminus \text{kg"*32 \ "m/s}$

$= 8 \setminus \text{kg m/s}$
