Question

When a person jumps horizontally off of the end of an unanchored boat in a lake, the person goes forward and the boat goes backward. This is an example of

Answer 1

The force of the person, who's jumping away from the boat, causes a:

equal and opposite reaction.

Hereby, causing the boat to move against this pushing, which, in turn, causes the boat to move backward.

Hope I helped ya!

Answer 2

Answer:

Newton's third law of motion.  

Explanation:

When a person jumps horizontally off of the end of an unanchored boat in a lake, the person goes forward and the boat goes backward. This is an example of Newton's third law of motion.

To an action, there is an equal reaction but also opposite. The action and reaction forces acts on two different objects. One object moves in forward direction while others moves in backward direction.

Hence, the given scenario is an example of Newton's third law of motion.
