AI Thread Summary

To calculate the magnitude of a vector given its coordinates, use the formula magnitude of vector u = sqrt(u1^2 + u2^2 + u3^2). Begin by identifying the coordinates of the vector in a three-dimensional space. A visual representation can aid in understanding the vector's direction and magnitude. It is important to make an effort in the calculation process, as forum rules suggest. Understanding these steps will help in accurately determining the vector's magnitude.

You can begin with a coordinate system. (PF rules require something of an effort is made by the requester...)

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:
