What is the Acceleration of the System?

AI Thread Summary
The discussion focuses on calculating the acceleration of a system involving three masses: a 4 kg mass moving up, a 2 kg mass sliding right on a table, and a 7 kg mass moving down, with friction between the block and the table represented by a coefficient of friction of 0.16. The gravitational acceleration is given as 9.8 m/s². Participants are encouraged to provide detailed descriptions or diagrams to clarify the setup for accurate assistance. The importance of adhering to forum rules for homework help is emphasized to prevent confusion. The goal is to determine the system's acceleration in m/s².

There is friction between the block and the table.
The suspended 4 kg mass on the left is moving up, the 2 kg mass slides to the right on the table, and the suspended mass 7 kg on the right is moving down. The acceleration of gravity is 9.8 m/s/s. What is the magnitude of the acceleration of the system? Answer in units of m/s/s.


(the picture won't work)
the µ = 0.16.

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'
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...
