When a sailor jumps out of a rowing boat, the boat moves backwards. This is an example of which of the following?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Newton’s third law of motion
Newton’s third law says that to every action there is an equal and opposite reaction, acting on a different body. To jump forward, the sailor pushes the boat backwards with his feet; the boat pushes him forward with an equal force, and the push he gives it makes the boat move backwards.
