Contour integral and problem of Quantum mechanics (Griffiths)

AI Thread Summary
The discussion revolves around solving Griffiths' problem 11.16 related to the 1-D integral form of the Schrödinger equation. The main question raised is about the inclusion of only one pole for each contour in the contour integral. It is clarified that a pole contributes to the integral only if it lies within the closed contour. This highlights the importance of contour selection in complex analysis as it pertains to quantum mechanics. Understanding these concepts is crucial for accurately applying contour integrals in quantum problems.

A pole contributes only if it is inside the closed contour. (I could be misunderstanding your question.)
 
Thread 'Collision of a bullet on a rod-string system: query'

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...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
