Answer:
Explanation:
Given
mass of block resting on wedge is
mass of block hanging vertically is m
coefficient of static friction
Let T be the tension in rope
thus for Equilibrium T=mg
is friction force
substitute the value of T
Also
Direction of Friction can either be directing upward or downward depending upon which side system goes after it is released from equilibrium or about to release.

The beetles consume the trees as food. So, if the trend continues, it’s likely that the trees will die out in the coming years
Explanation:
Well, Bianca, I'll tell ya. You really haven't told us enough to completely define exactly what's going on here. In fact, now that I look at it carefully, you've told us nothing at all ... only asked a question based on zero given information.
IF you're talking about an object like a baseball or a rock or another projectile of some kind, and IF the object has no jet engines on it, and IF it has been tossed, launched, thrown, or otherwise sent on its way to somewhere other than the place it left from, and IF it's OK to ignore the effects of air resistance, then ...
-- the only force acting on the object is the force of gravity
-- gravity only points down
-- gravity has no effect on horizontal velocity
-- horizontal velocity is <em>constant</em>, and <em>doesn't change </em>as time goes on.
But IF any of these things is different, then you can forget everything I said. I'm just guessing.
