Answer:

First: 1st law

Second: 3rd law

Third: 2nd law

Step-by-step explanation:

The first scenario is the first law of motion, which states that an object remains moving or at rest unless a force is acted on it. In this case, the passengers want to continue moving, but the seatbelts exert a force on them.

The second scenario is the third law of motion, which states for every action, there is an opposite and equal reaction. So, a person pushes on the water, and the water pushes on the person.

The third scenario is the second law of motion because if we would look at the formula of the second law, it would be F=ma, since bookcase with books has a larger mass, it need a large force to be moved.
