Question

A 2.0 kg wood box is help stationary against a vertical wood
wall while you push upward on it at a 45° angle. For wood
on wood, the coefficient of kinetic friction is µ = 0.20 and
P₁ = 0.30.
Find (1) Fmin the minimum push force needed to stop the
box from sliding along with (2) Fmax the maximum force
that can be applied before the box slides. Also find (3) the
frictional force vector when F
(Fmax + Fmin)/2.
