Coefficient of Kinetic friction problem

AI Thread Summary
Harry is tasked with finding the coefficient of kinetic friction for a sled with a mass of 110kg being pulled at constant velocity on a level surface. The downward force calculated for the sled is 1079.1 N. Initially, the student faced confusion due to a lack of information on the worksheet, which was later confirmed to be a typo. After obtaining the missing details, the student successfully solved the problem. The discussion highlights the importance of complete information in physics problems for accurate calculations.

Homework Statement


Harry pulls a sled with a mass of 110kg along a level surface of the forest in a straight line at a constant velocity. What is the coefficient of kinetic friction between the surface and the sled?


Homework Equations


f_k = \mu_k N
Fg=ma

The Attempt at a Solution


I calculated the downward force of the sled, which is 1079.1 N. After that I'm not really sure what to do. The other examples we did in class gave an angle, but this one doesn't seem to have one.
Thanks in advance

I would expect more information to be given with this.
 
Well, I asked my teacher and it was a typo on the worksheet. There is suppose to be more information. I solved it after I got the information. Thanks anyway.
 
Ahh, the old typo on the worksheet. I'm sure that frustrated more thana few students. At least its sorted now.
 
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...
