Kinetic friction, pulley, inclined plane

AI Thread Summary
The discussion revolves around a physics problem involving two blocks connected by a string over a pulley, moving down an inclined plane with kinetic friction. The kinetic frictional forces acting on the blocks are specified, with block 1 experiencing a force f and block 2 experiencing a force of 2f. The user is attempting to determine the coefficient of kinetic friction for block 1 but is unsure how to proceed after calculating the normal force. A suggestion is made to create a force diagram to clarify the forces at play and identify where the confusion lies. The conversation emphasizes the importance of visualizing forces in solving such problems.

Homework Statement




blocks 1 and 2 of masses m1 and m2 respectively, are connected by a light string. these blocks are further connected to a block of mass M by another light string that passes over a pulley of negligible mass and friction. blocks 1 and 2 move with constant velocity v down the inclined plane, which makes an angle (theta) with the horizontal. the kinetic frictional force on block 1 is f and that on block 2 is 2f.

Determine the coefficient of kinetic friction between the inclined plane and block 1.

Start by making a force diagram and showing what work you have done so far. That way, we can see where you are stuck. ALWAYS start this kind of problem by making a force diagram (aka free-body diagram).
 

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...
