How do momentum, impulse, and GPE factor into solving physics questions?
AI Thread Summary
Momentum, impulse, and gravitational potential energy (GPE) are crucial concepts in solving physics problems, especially in competitive contexts. Understanding the relationships between these concepts can aid in analyzing motion and energy transfer in various scenarios. Participants in the discussion emphasize the importance of breaking down problems step by step to identify where confusion arises. Clarifying the application of formulas related to momentum and GPE can significantly enhance problem-solving skills. Seeking assistance and verifying calculations is essential for mastering these physics concepts.

this is what I've got so far but I am not sure if its right.
thats what I've figured out so far but i need to verify this.
please help.

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:
Let's declare that for the cylinder,
mass = M = 10 kg
Radius = R = 4 m
For the wall and the floor,
Friction coeff = ##\mu## = 0.5
For the hanging mass,
mass = m = 11 kg
First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on.
Force on the hanging mass
$$mg - T = ma$$
Force(Cylinder) on y
$$N_f + f_w - Mg = 0$$
Force(Cylinder) on x
$$T + f_f - N_w = Ma$$
