What force is needed to move a 10 pound block up a vertical wall at a constant speed by pushing at an angle of 53 degrees with the vertical? Mu=0.3

At what minimum angle with the vertical would you be unable to push the block at all regardless of how large the force is?

2. Relevant equations

Y: Fcos53-weight-(Mu*NormalForce) = 0

NormalForce-Fsin53=0

3. The attempt at a solution

I solved the force needed to push the block up a constant wall which is 27.6 lbs. However, I'm unsure of the second part of the question.
