Hi can anyone help me with this problem.. Picture is included.. I am kinda lost.. thank you so much
m = 0.4Kg
m = 0.4Kg
Circular Movement: Understanding m = 0.4Kg - Helpful Picture Included!
AI Thread Summary
The discussion revolves around a physics problem involving circular movement with a mass of 0.4 kg. The original poster is seeking assistance but has not clearly stated the specific question, which is crucial for receiving help. Participants emphasize the importance of providing detailed information to facilitate effective responses. The focus is on determining the tension in the cables related to the problem. Clarity in the question is essential for meaningful assistance in physics discussions.
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
$$T + f_f - N_w = Ma$$
