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.
