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?

Answer 1

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.
