To determine the walker's momentum, we will use the formula for momentum in physics:
[tex]\[ p = m \times v \][/tex]
where:
- [tex]\( p \)[/tex] is the momentum,
- [tex]\( m \)[/tex] is the mass of the object,
- [tex]\( v \)[/tex] is the velocity of the object.
In this case, we are given:
- The mass ([tex]\(m\)[/tex]) of the person is [tex]\(15 \)[/tex] kg.
- The velocity ([tex]\(v\)[/tex]) of the person is [tex]\(10 \)[/tex] m/s.
Now, let's calculate the momentum:
1. Start with the formula for momentum:
[tex]\[ p = m \times v \][/tex]
2. Substitute the given values for mass and velocity into the formula:
[tex]\[ p = 15 \, \text{kg} \times 10 \, \text{m/s} \][/tex]
3. Perform the multiplication:
[tex]\[ p = 150 \, \text{kg-m/s} \][/tex]
Therefore, the momentum of the walker is [tex]\(150 \, \text{kg-m/s}\)[/tex].
Based on this calculation, the correct option is:
A. 150 kg-m/s
