So the problem begans like this

A block of mass 8kg is pushed up against a wall by a force P that makes a 50 degree angle with the horizontal. The coefficient of static friction between the block and the wall is 0.249. Determine the possible values for the magnitude of P that allow the block to remain stationary.

They ask for the miniumum P that will allow the block to remain stationary but I'm not sure how to set it up.

We know that at Fsmax = UsN, and anything below it is Fs = F . But what exactly is F?

Fy = Psin50 - Fs - mg

Since its still stationary Fy is 0

Does F = Fsmin + mg?

if so 0 = Psin50 - (Fsmin + mg)

but when i plug in the values I get the wrong answer still

can anyone give me some tips? Thanks!
