Prove that coefficient of friction is independent of mass?

AI Thread Summary
The discussion focuses on proving that the coefficient of friction is independent of mass for a rider on a merry-go-round. Participants express confusion about the problem's requirements, particularly regarding the conditions of motion, such as whether slipping occurs. The key equations mentioned include the frictional force equation Ff = u*Fn and the normal force equation, likely Fn = mg. There is a consensus that additional information about the friction conditions is necessary to solve the problem effectively. Overall, the discussion highlights the need for clarity in the problem statement to facilitate a mathematical proof.

Homework Statement


Prove mathematically that the coefficient of friction is independent of the mass of a rider at a fixed location from the center on a merry go round.


Homework Equations


F = ma?


The Attempt at a Solution


I honestly don't know - I can't find two starting equations...

Yikes, is that the COMPLETE question? There has to be something more about the friction. Are we slipping on the merry go round, or going at the maximum speed before slipping begins?

One formula will be good old Ff = u*Fn.
Then we need a formula for Fn - probably mg, and another for Ff. That's what is missing from the question - something about the friction.
 

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...
