ok, so i got this assignment for the march break and our teacher hit us with this weird question.
You are pushing horizontally on a 3.0kg block of wood, pressing it against the wall. if the coefficient of friction between the block and the wall is μ = 0.60, how much force must you exert on the block to keep it from slipping down the wall?
so, i came to the conclusion that Fg = 29.4N, I am guessing Ff would be opposite to it, but i don't know if it will equal Fg. Also i think that the normal force will be oppsite to the applied force in this question, no? The thing is, i don't know how to solve for any of these values. would i assume that Ff equals Fg then use Ff = μ * FN and solve for FN? would that work?... i don't know...
... Any help would be very much appreciated. Thanks.
