Question

if a man jumps out from a boat ,the boat moves backwards .why​

Answer 1

Answer:

⭕ This is because of Newton's third law of motion according to which "every action has an equal and opposite reaction."

• When a man jumps out from a boat, he applies a force on it due to which the boat moves backwards. Now, in return an equal force is exerted by the boat on the man which helps him to jump out of it.

Answer 2

Explanation:

While jumping, the man has to have some kind of energy or a platform to propel his body

In this situation, the boat is the platform

As per Newton's third law

Every action force has an equal and opposite reaction.

Now,

As the body moves in this direction

<<<<

The boat goes in

>>>>

The man pushes the boat in order to push his body in the opposite direction.

It is the same as jumping on ground

We exert force on the ground and propel ourselves in the air

Both are opposite.

This is why if a man jumps out from a boat, the boat moves backwards.

Hope it helps!
