What is the displacement of the wrench?

AI Thread Summary
The discussion revolves around calculating the displacement of a wrench dropped from a building after 7 seconds, using gravitational acceleration (g = 9.8 m/s²). Participants emphasize understanding the physical meaning of g and whether it changes during the fall. They suggest using kinematic equations to solve the problem once these concepts are clarified. The conversation highlights the importance of grasping fundamental physics principles to approach the calculation effectively. Overall, a clear understanding of gravitational acceleration and kinematic equations is essential for determining the wrench's displacement.

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...
