Jane has a mass of 50 kg. She pushes on a 60 kg rock with a force of 120 N. What force does the rock exert on Jane?
Answers
Answer:
120 N
Explanation:
By Newton's third law of motion,
A force has an equal and opposite reaction.
--> The force exerted by Jane on rock = Force by rock on Jane.
--> Force by rock on Jane is 120N
The force that the rock will exert on Jane will be 120 N.
Newton's third law states that every action has an equal and opposite reaction.
This law is called the law of action and reaction.
This means when two bodies are in contact with each other, both the bodies experience equal force but in opposite direction.
The actual force which is applied is called the action force and the force that is produced in response to the action force on the other body is called the reaction force.
When Jane pushes the block with 120 N, the block will exert equal magnitude of force but i the opposite direction.
