So, lets call this numerator n. If written into a fraction, it wold look something like this. n/n+2 You add one to both n+1/n+3 You should be able to solve from here Cheers. Jeanne

OK, so lets call the numerator n. The denominator is 7 more than twice the numerator. Put into an equation, it would look like this. n/2n+7 You add 7 to both, and it will look like this: n+7/2n+14 You should be able to solve from here. Cheers! Jeanne

I know the work done is W = ì X mgcosè X d and W is Ui+ W= Kf which is 54-(25*3.3)=-33.5 so W = ì X mgcosè X d and so ì= (W/(mgcosè X d)) and mg=25N so what is cosè? and i think d is the hypotenuse?

Yes, your equation is right so if you just plug in your given numbers for P=mgcos20-(mgsin20/uS) you should get the correct answer.

9. ## Physics

I am trying your equation from for P. I have a feeling it will come out as a negative force and if you apply a perpendicular force it will only increase the contact force and thus not move the box, but let me see.

12. ## Physics

Yeah I got that, but I was hoping you could explain what you defined as the x' and y' component of each like in terms of cos and sin seeing that we might not be on the same page so i cant check ur answers exactly if i use something different.
