Question

Define Newton's third law of motion. Explain why it is difficult for a fireman to hold a hose , which ejects large amount of water at a high velocity?

Answer 1

Newton's Third law of motion

Every action has an equal and opposite reaction

Explanation

A fireman ejecting water at high speed from a water hose experiences the same amount of force that is exerted by the water in leaving the hose

m1v1(actionary momentum)= - m2v2(Reactionary momentum)

Note

these concepts only hold true in inertial frames and when the forces are conserved

Answer 2

Heyyyyy!!!!


Newton's third law states that for every action there is an equal and opposite reaction.it is also known as the action-reaction law.

It is difficult for a fireman to hold a hose while ejecting water because the ejection of water also puts force on the hose towards us which makes it difficult to hold
