Friction Kinetic Kinetic friction

AI Thread Summary

To find the coefficient of kinetic friction for a 20kg sled being pulled with an 80N force at a 30-degree angle, additional information such as acceleration is necessary. Without acceleration, the frictional force cannot be determined. The discussion emphasizes the importance of having complete data to solve the problem accurately. Participants suggest that if acceleration is provided, it can be used to calculate the coefficient of kinetic friction. The conversation highlights the need for comprehensive details in physics problems.

I don't believe you can find it with just that information. Did they not give the acceleration?

If they did, what did you try for this problem?

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
