    Ratio Speed
AI Thread Summary
The discussion focuses on optimizing energy efficiency through speed ratio analysis, particularly in relation to understanding the center of mass in a system involving two boats. Participants express confusion about calculating speeds when only masses are provided and the implications for the center of mass when objects are in motion. The center of mass is noted to be initially at rest, raising questions about its movement when actions, like throwing balls, occur. There is also frustration over missing problem statements that hinder effective assistance. Overall, the conversation emphasizes the importance of clarity in problem-solving related to energy conservation and momentum.

The Attempt at a Solution


I started out using the above formula, but I don't understand how to get the speeds when only the masses are given.

When all is said and done, where is the center of mass of the system?

We haven't really discussed center of mass in detail in Momentum, but is it in between the two boats?
 
It is between the two boats, but that is not the point. It is initially at rest and you need to consider the question whether the center of mass will start moving or not when these guys start throwing balls around.

Why did you edit out the statement of the problem? How can I provide more help if I cannot see it?
 

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...

Thread 'A cylinder connected to a hanging mass'

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...
