AI Thread Summary
The discussion revolves around a physics problem involving simple harmonic motion and energy calculations after a collision, specifically where the energy is expressed as mgh/2. The original poster is struggling to formulate the energy equation post-collision and is seeking assistance with the actual calculations. Forum members emphasize the importance of demonstrating prior effort in solving the problem to receive help. They also encourage the use of LaTeX for clarity in presenting equations. Adhering to homework guidelines is crucial for effective assistance.
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...
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:
TL;DR Summary: Will motion in y direction eventually stop
If an object moves with initial velocity in both x and y direction and acceleration in only the x direction. If the angle of movement with the x axis will eventually become zero does that mean the object will eventually not move in the y direction.
