Q: The kayak’s motion in the water is an example of classical addition of what?


Read this paragraph and choose the correct option from the provided answers:

If you’ve ever seen a kayak move down a fast-moving river, you know that remaining in the same place would be hard. The river current pulls the kayak along. Pushing the oars back against the water can move the kayak forward in the water, but that only accounts for part of the velocity. The kayak’s motion is an example of classical addition of velocities. In classical physics, velocities add as vectors. The kayak’s velocity is the vector sum of its velocity relative to the water and the water’s velocity relative to the riverbank.

 Choices:

- momentum

- force

- acceleration

- velocities


A:
velocities
