Answer:
The whale's momentum is approximately 2476.7 kg m/s
Explanation:
Recall that the definition of linear momentum is the product of the object's mass (in our case the whale's mass) times the object's velocity (in our case 0.273 m/s).
Therefore the whale's momentum (P) is:
P = M * v = (9072 kg) * (0.273 m/s) = 2476.656 kg m/s
which can be rounded to one decimal to: 2476.7 kg m/s
