Newtons third law question- Action reaction pair

AI Thread Summary
In the discussion about Newton's third law, it is clarified that when a 2000kg car pushes a 1000kg garbage can at constant speed, the forces involved are equal in magnitude but opposite in direction. The force exerted by the car on the garbage can (CB) is equal to the force exerted by the garbage can on the car (BC), as expressed by the equation Fcb = -Fbc. The explanation provided through free body diagrams (FBDs) supports this understanding of action-reaction pairs. The conclusion confirms that the forces are indeed equal, aligning with Newton's third law. This reinforces the fundamental principle that for every action, there is an equal and opposite reaction.

Homework Statement



A 2000kg car pushes a 1000kg garbage can at constant speed . The car exerts a force of magnitude CB on the garbage can, and the garbage can exerts a force BC on the car. Which force has greater magnitude, or are they equal? explain

Homework Equations


Fcb=-Fbc


The Attempt at a Solution



Esentially, I drew 2 FBD's and showed one for the car with a force on the right CB ... the second FBD of the garbage can has a force pointing to the left of BC... which is equal and opposite magnitude of CB

Basically i just explained Newtons third law

Is this correct?

That is right, and it is just Newton's third law, indeed.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
