Average Coefficient Coefficient of friction Friction

AI Thread Summary

To determine the average coefficient of friction for a skier gliding up a 22° incline, the problem involves analyzing the forces acting on the skier, including gravitational force and friction. The skier's initial speed is 11 m/s, and they travel 13 m up the slope before stopping. The key to solving the problem lies in applying the equations of motion and understanding how mass cancels out in the calculations. The discussion highlights the need for assistance in setting up the equations and clarifying the role of mass in the friction calculation. The average coefficient of friction can ultimately be derived from the skier's deceleration and the incline's angle.

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:
