AI Thread Summary
The problem involves three blocks, with block 1 having mass M and block 2 having mass 2M, accelerating at 0.500 m/s² after being released from rest. To find the coefficient of kinetic friction between block 2 and the table, it is essential to analyze the forces acting on each block and apply Newton's second law. By setting up equations for each mass, one can derive a system of equations that can be solved simultaneously to determine the value of the coefficient of kinetic friction (μ). A diagram is suggested to visualize the forces involved, aiding in the analysis. The discussion emphasizes the importance of clearly stating the problem and showing the work involved in reaching the solution.

Take each mass in turn, analyze the forces on it, and apply Newton's 2nd law. You'll get three equations that you can solve together to find μ.
 

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'

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...
