To solve for the walker's momentum, you can use the formula for momentum:
[tex]\[ \text{Momentum} = \text{mass} \times \text{velocity} \][/tex]
Here, the given values are:
- Mass ([tex]\(m\)[/tex]) = 15 kg
- Velocity ([tex]\(v\)[/tex]) = 10 m/s
Substitute the given values into the formula to find the momentum:
[tex]\[ \text{Momentum} = 15 \, \text{kg} \times 10 \, \text{m/s} \][/tex]
[tex]\[ \text{Momentum} = 150 \, \text{kg} \cdot \text{m/s} \][/tex]
So, the walker's momentum is [tex]\(150 \, \text{kg} \cdot \text{m/s}\)[/tex].
Therefore, the correct answer is:
B. [tex]\(150 \, \text{kg} \cdot \text{m/s}\)[/tex]
