Question
Although larger than the Atlantic walrus, the Pacific walrus can swim with a speed of about 9.7 m/s. If the momentum of a swimming walrus is 10,700 kg • m/s, what is its mass?

To find the mass of the Pacific walrus, we can use the formula for momentum:
\[
\text{Momentum} = \text{mass} \times \text{velocity}
\]
Given that the momentum (\(p\)) is 10,700 kg•m/s and the velocity (\(v\)) is 9.7 m/s, we can rearrange the formula to solve for mass (\(m\)):
\[
m = \frac{p}{v}
\]
Now we can substitute the values:
\[
m = \frac{10,700 \, \text{kg•m/s}}{9.7 \, \text{m/s}}
\]
Calculating this gives:
\[
m \approx 1,103.1 \, \text{kg}
\]
Therefore, the mass of the Pacific walrus is approximately **1,103.1 kg**.
