Conservation of Energy and Momentum

AI Thread Summary
The discussion focuses on the relationship between energy and momentum in a physics problem involving a swinging mass. The velocity at the bottom of the swing is given by V = Sqrt(2gh), but there is uncertainty about how to relate this to the velocity of point A. It is suggested that angular momentum of mass B could equal its linear momentum, but clarification is needed on the pivot's fixed position. The participants are encouraged to provide answers to earlier parts of the problem to facilitate solving the subsequent part. Understanding these principles is crucial for accurately applying conservation laws in this context.

The Attempt at a Solution


I know that the velocity of mass at the bottom of the swing is
V = Sqrt(2gh), but I'm not sure how to get from there to the velocity of A. Is it as simple as Angular momentum of B = Linear Momentum of B?

That would be true if the pivot were fixed.

What are your answers to parts a and b? (Those are the keys to solving c.)
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

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 $$T + f_f - N_w = Ma$$ There's also...
