    Forces Friction
AI Thread Summary
To solve the problem of a box sliding up a ramp due to the mass of an attached box, start by calculating the net force using Fnet = ma, where 'm' is the combined mass and 'a' is the given acceleration. Next, determine the normal force, which is essential for calculating kinetic friction, using the equation for gravitational force (Fg = mg) and considering the angle of the ramp. Kinetic friction can be found by multiplying the friction coefficient by the normal force. For the tension force, analyze the forces acting on the system, including the weight of the attached box and the frictional force. Understanding these relationships will lead to the correct calculations for tension and kinetic friction.

[solved] Forces and friction

Hi guys :]

Homework Statement


A box (A) slides up a ramp due to the mass of the attached box (B).
Given the acceleration and ramp length, determine the force of tension and force of kinetic friction.


Homework Equations


Fnet=ma
Fg=mg

The Attempt at a Solution


I only got as far as finding the Fnet by multiplying the combined masses and given acceleration. Where do I go from here?
I don't need numerical values, just.. can someone enlighten me on how I should approach this question, so I can find the kinetic friction and tension forces?

Any help is greatly appreciated, thanks :redface:!

I think kinetic friction is found by multiplying the friction coefficient by normal force. So the normal force must be found. Not really sure about tension.
 

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...
