T= 2pi*sqrt(L/g)
The Attempt at a Solution
T= 2pi*sqrt(0.325/9.8)=1.14 s
That seems like a reasonable answer.
Pendulum pulse vertical flick period
AI Thread Summary
The discussion revolves around the calculation of the period of a pendulum using the formula T= 2pi*sqrt(L/g). The initial calculation of the period was found to be 1.14 seconds, but this was deemed incorrect. Participants questioned the justification for using the simple pendulum formula, suggesting that the motion of the hanging mass and the specific physics context should be considered. There is an emphasis on providing a complete problem statement and detailed solution attempts in future discussions. Clarity and justification in problem-solving are crucial for accurate physics analysis.

Incorrect.
What is your justification for using the formula for the period of a simple pendulum? Is the motion of the hanging mass relevant here? What type of physics is being asked about?
In future, please type out your problem statement and solution attempts. Justify your approach and steps.

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:
F1=(5000+200)g=5200*10=52000N --> F2=(5000+100)g=5100*10=51000N ?
