Calculating Force of Friction: 36N Applied to 6kg Cart with 5.5m/s Acceleration

AI Thread Summary
To calculate the force of friction acting on a 6 kg cart with a 36N applied force and an acceleration of 5.5 m/s², the net force must first be determined using F = ma, which results in a net force of 33N. The force of friction can then be calculated by subtracting the net force from the applied force, yielding a frictional force of 3N. Participants in the discussion express confusion about the physics concepts involved, particularly regarding net force and friction calculations. Clarification on using the formulas correctly is sought, emphasizing the need to understand the relationship between applied force, net force, and friction. Understanding these principles is essential for solving similar physics problems effectively.

stupid forces of friction !

1. a force of 36N is applied to a 6kg cart. If the cart accelerates at 5.5m/s what is the force of fricrion



im not even sure what to do, I am in physics 20 and not very good at it please help this is my atempt



Ffriction=Fn*u idk what anthing means? haha please help ?

it dosent tell me a net force, i have no idea what to go. i tried f=umg but it didnt come out right i know the answear is 3 i just don't know how toget there
 


Find the net force using F=ma.
Try to go from there

Use F = ma. What should be F then? How will F get that value?
 

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'

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...
