A 9072 kg humpback whale is swimming at a speed of 0.273 m/s. what is its momentum?

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

1/0.14nm = 10^10/1.4 a lot
