AI Thread Summary

The discussion centers on solving the equation d(λmu) in the context of relativistic energy. The user seeks assistance in demonstrating that d(λmu) equals m(1-(u^2/c^2)^(-3/2) du. They provide the equation for λ as λ = 1/√(1-(u^2/c^2)) and mention attempting to solve the problem through integration and differentiation. However, they express confusion and request others to show their work for clarity. The thread emphasizes the need for clear steps in solving the equation.

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 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
