Yes, that is exactly what I was looking for! Thank you all very much!

So I've done a calculation and I'm not really sure if it's what I am looking for, or really how to interpret it Ffriction=μN ΣFx=T-Ffriction-Fþverkraftur=0 ΣAFy=N-Fg⋅yA=0 Σ T-Fg⋅B= 0 FgA=mA*g*sin(θ)-mag*cos(θ) FyB= mB*g T-Ffriction-mA*g*sin(θ)=0 N-mAg*cos(θ) T-mBg=0 → T=mBg...

I have an inclined pulley with inclination 30°. There is mass A on top of it equals 2 kg. And over a frictionless pulley there is a mass B with weight 0,83 kg. The text says that the coefficient of friction is 0,18 between mass A and the incline. I need to know the acceleration. and I also have...

I remember the free body diagrams. Simultaneous equations isn't that like substitution? or elimination? Mostly the confusion is that in Iceland we sometimes use different letters in equations so I put in the wrong value but I'm getting the hang of it more and more everyday. Mostly it´s...

It's been like 3 years since I did this last and that time it was in icelandic. I'm having difficulty with the word problems.

I'm just completely stumped here, I'm sorry.

I'm Brynhildur and I come from Iceland! I am studying Engineering Management at the University of Reykjavík. First time studying in English so I've been using the internet to get some extra information :D I've already found this page to be very useful and informative! :D

[Moderator note: Moved from General Physics so no template.] An object slides down an inclined plane where there is friction. The time it takes the objects to slide down the plane is 5/4 times longer than the time it takes the same objects to slide down the plane without friction. Calculate the...
