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.
$$
p = m \cdot v
$$
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.
