A3.06kg wood block is pressed against a vertical wood wall by a force applied at angle ϕ=32.6° to the horizontal. if the block is initially at rest, and μs=0.313, what force would you need to apply to begin moving the box up the wall?

Let applied force against the wall is F

now the Normal force on the block is given by

now friction force on the block will be given as

now net downwards force on the block will be

now this net downward force must be counterbalanced by upwards applied force

so it required 109.1 N force to move it upwards
