The first friend Whatever push she exerts on the tree briefly or otherwise, the pushback by the tree will be equal and opposite. That's Newton's 3d law Submit Provide Feedback Next >

Answer 1

The first friend. Whatever push she exerts on the tree, briefly or otherwise. The pushback by the tree will be equal and opposite. Thats Newtons third law.

Because According to Newtons third law of motion, every action has equal and opposite reaction. and the reaction force (or pushback) do not depend on strength or how fast the force is applied. But its always equal and opposite.
