Acceleration of a Pulley System?

AI Thread Summary
The discussion revolves around calculating the acceleration of a pulley system involving two bodies with different weights and friction coefficients. The user is confused about how to approach the problem differently for three scenarios: when Body B is at rest, moving up the incline, and moving down the incline. They express uncertainty about the relevant equations needed for each situation and seek clarification on the differences in solving for acceleration in each case. Additionally, a broken link to a reference material is mentioned, which hinders further assistance. Understanding the impact of friction and the forces acting on the bodies is crucial for solving the problem correctly.

Homework Statement


Body B in the figure weighs 102N and Body A weighs 32N, The coefficients of friction between B and the incline are Ms=0.56 and Mk=0.25. Find the acceleration of the system if
a) B is initially at rest
b) B is moving up the incline
c) B is moving down the incline


Homework Equations


i don't understand which equations i would need

The Attempt at a Solution


what's the difference in situation between a, b, c i don't understand how i could solve them differently
i am so confused!
 
Physics news on Phys.org
this is the original question example 5
i get how to get the acceleration, but what's the difference between part a,b,c

opps: forgot the link: people.uncw.edu/ganl/phy201
go to chapter 6, example 5:)

I gave a post about this on the other problem.
Your link does not work so if someone else wants to help tonight you might want to change it.
 

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...
