Hi guys, I have a dyanamics question to ask. Thanks for the help! In the scenario there is two objects-one the box and the hand pushing it When i push an object, there will be a force acting on the object and hence a reaction force acting on my hand. So, if i were to apply 10N of force on a box i would also receive 10N of force acting on my hand. With just this 2 pieces of information in mind, would it be possible to tell what is the force acted on my hand (FBD of hand) to counteract the 10N reaction force? Or will the minimum force exerted by my hand equal to the force that i exert on the box meaning 10N of force such that they counteract each other so net force of hand is 0N - or will the force i exert on my hand be 20N such that the net forces of both objects must be equal (if 20N of force exerted on hand net force=20N-10N=10N and on the box, net force=10N of force exerted on the box)? So, is there a rule to follow, like will the two bodies have the same net force, or same acceleration or is it up to me to exert the force on my hand to counteract the box just that i must have a force that is equal to the force exerted on the object itself (or else i will have an opposite net force which probably doesn't work). I'm unsure about this as there are two bodies to consider and I don't know how to determine the forces of the two object. Thanks for the help!
