Solving for Min Speed with Applied Newton's Law

AI Thread Summary
To determine the minimum speed using Newton's Law with only a radius provided, the formula used is √(F*r/m), which simplifies to √(g*μ*r). The main challenge is solving for the coefficient of friction (μ) without additional information. Clarification of the problem statement is necessary for further assistance. The discussion highlights the importance of complete problem details for accurate solutions.

I can't figure out how to solve for the minimal speed needed if they only provide me a radius. I am using this formula:

\sqrt{\frac{F*r} {m} }

I simplified to:

\sqrt{g*\mu*r}

,but i don't have no idea how to solve for /mu.

Please some help.

Sorry I already solved it. Thanks anyway. I will be asking some of these days.
 

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...
