Lets say I have a massive rod laying on a table with little froction, screwed into the table on one side to become our pivot point, and I lay next to it with my feet pointing towards the rod.
First scenario: I position myself very close to the pivot point and push, the rod rotates and I move across the table too.
Second scenario: I now position myself far from the pivot point and close to the free rotating side of the rod, and I push with my legs again with the same force and for the same duration of time.
Is there any difference in terms of how far I will go after I push and come to a stop where that little friction stops me between these two scenarios?
Is there any difference to how far will the rod rotate around the pivot point before that little friction stops it? (Assume I and the rod have have the exact same friction acting to both of us, so they cancel each other out)
Attempt at solution: I think I will move the same distance in both scenarios due to the impulse being the same, but I do not know about the rod, does me applying the same force for the exact same amount of time but at different distances from the pivot point affect how far the rod will rotate, I don't know
Thank you
