Center of mass of two particle system (q45)

AI Thread Summary
To find the center of mass of a two-particle system, start with the mathematical definition of center of mass. Taking the first derivative gives the velocity of the center of mass, and the second derivative provides its acceleration. Understanding how the acceleration of the center of mass relates to the individual masses' accelerations is crucial for problem-solving. The formula Ma_cm = summation of individual ma is effective in solving these types of problems. This approach has successfully led to the correct solution.

Hi, I do not know how to get started for the following question,
http://tinyurl.com/yueh5m
can somebody help?

Start with the mathematical definition of center of mass. Then take a derivative to find the velocity of the center of mass. And another derivative to find its acceleration. Once you see how the acceleration of the center of mass relates to the accelerations of the individual masses, then you can solve this problem.
 
Thanks, using the formula Ma_cm = summation of individual ma, has helped me successfully solved the problem. it is 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...

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...
