Question

70 kg man push a 50 kg man by force of 50n what force has the 50 kg man pushed

Answer 1

This question tests the concept of Newton's third law of motion.

It states that :

For every action there is an equal and opposite reaction.

The 70kg man applies 50 N to the 50kg man. This gives us the action force.

The reaction force is what the 50kg man applies back.

This force is equal and opposite to the action.

And thus it is equal to 50N
