Mastering physics problem regarding speed and tension

AI Thread Summary
The discussion focuses on determining the speed at which the tension is equal in both wires attached to a 2.0 kg sphere revolving in a horizontal circle. Participants suggest analyzing the vertical forces acting on the sphere in relation to the tension components and applying equations for horizontal forces based on angular velocity and radius. The conversation emphasizes finding the lengths of the wires to calculate the radius needed for the equations. Ultimately, the solution involves substituting values to derive the angular velocity. The user successfully finds the answer with the help of hints provided.

Two wires are tied to the 2.0 kg sphere shown in the figure View Figure . The sphere revolves in a horizontal circle at constant speed.

For what speed is the tension the same in both wires?

What is the tension?



I reallllly need some hints to figure the first part, and the second part...thank you

What is the tension?
Find the vertical force on the sphere in terms of the vertical components of the tension (1).

Then write the equation (2) for the horizontal force on the sphere (in terms of \omega and r

Then find the lengths of the wires in order to find r.

Substitute r into (2) (both tensions = T) and use T from (1) to find \omega

yeah, got the answer, thanks
 

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...
