Homework Statement
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.
Homework Equations
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.
