What is the Direction of x Using the Right Hand Rule?

AI Thread Summary
The discussion revolves around determining the direction of x using the right hand rule, given that z is east and y is south. The initial confusion arises from the incorrect assumption that x could also be south, which is already defined by y. After clarification, it is established that x corresponds to the upward direction. The correct application of the right hand rule confirms that x is indeed up. This conclusion resolves the initial uncertainty regarding the orientation of x.

you know z=east so that -z=west and y=south so that -y=north so what else is left for x?

Yes. Rotating y into z gives x for your thumb.

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...
