(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A block rests on a wedge inclined at an angle [tex]\theta[/tex]. The coefficient of friction between the block and the plane is [tex]\mu[/tex].

Let the wedge move with horizontal acceleration a to the right. Assuming

that tan [tex]tan(\theta) < \mu[/tex], find the minimum value of a for the block to remain on the wedge without sliding.

Also find the maximum value of a.

2. Relevant equations

3. The attempt at a solution

[tex]mgcos(\theta)+masin(\theta)=F_{normal};

\tex{mgcos(\theta)+\mu (F_{normal})=macos(\theta);

a=\frac{g(sin+\mu cos}{cos - \mu sin}[/tex]

which gives wacky limiting values and isn't a range at all but just one value.
