Discontinuous voltage graph for bullet going through metal coils

AI Thread Summary
The discussion centers on the discontinuous nature of voltage graphs V1 and V2 as they intersect the time axis in the context of a bullet passing through metal coils. Participants suggest that the discontinuity appears to be a drawing issue rather than a physical phenomenon, as the induced voltage should be continuous based on the change in the magnetic field. The confusion regarding the graphs does not seem to hinder the ability to solve the homework problem but is more of a curiosity. It is recommended to seek clarification from a teaching assistant or professor if needed. Overall, the focus remains on understanding the graphical representation rather than the underlying physics.

However, dose anybody please know why the graphs for ##V_1## and ##V_2## are discontinuous where they cross the time axis?

Many thanks!

It only looks like a drawing issue, not something to do with the physics. The voltage induced is just proportional to the change in the B-field through the loops, which is certainly continous in the real world. Is this confusion affecting your ability to solve your homework problem, or just a curiousity at this point?

If (b), I would recommend that you just ask a TA or the professor informally when you next see them.

Thanks for your help @berkeman ! Just (b) at this point, but it does sound like it drawing issue as you mention.

Thank you!
 
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...
