How Far Does the 40Kg Skater Move?

AI Thread Summary
The discussion centers on a physics problem involving two skaters of different masses pulling themselves along a 10-meter pole. The calculations show that the center of mass (xcom) is at 3.8 meters, indicating the 40 kg skater moves 6.2 meters towards the 65 kg skater. Participants express surprise at the simplicity of the problem, contrasting it with their typically challenging assignments. The consensus is that the problem is straightforward and easy to solve. Overall, the discussion highlights the ease of this particular physics question compared to others.

Hi, I must be doing something wrong...because i found this question wayyyy too easy.

Two skaters, one with mass 65Kg and the other with mass 40Kg stand on the ice rink holding a pole 10 m long and a negligible mass. Starting from the ends of the pole, they pull themselves along the pole until they meet. How far does the 40Kg skater move?

\frac{m2}{m1+m2} d

xcom=3.8m

m2 travels : 10m - 3.8m

m2 travels 6.2m

Is it as easy as this?

Looks like it. Your other one was even easier :wink:
 
it just doesn't make sence...Our assignments are always difficult

weird...
 
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...
