How can you calculate the momentum of a person with a mass of 126 kg running at a velocity of [tex]$5 \, \text{m/s}$[/tex]?

Answer :

To calculate the momentum of the person, we use the formula for momentum:

$$
p = m \cdot v
$$

where:
- $m$ is the mass,
- $v$ is the velocity.

Given:
- Mass, $m = 126 \text{ kg}$
- Velocity, $v = 5 \text{ m/s}$

Substitute the given values into the formula:

$$
p = 126 \text{ kg} \times 5 \text{ m/s}
$$

Simplify the calculation:

$$
p = 630 \text{ kg} \cdot \text{m/s}
$$

So, the momentum of the person is $630$ kg·m/s.
