Answer:
If one assumes that F will just start the object to move:
F = μ Wa cos θ where θ is the angle of the applied force
and Wa is the apparent weight of the object
μ = F / (Wa cos θ)
Note that Wa = W - F sin θ true weight less component of applied force
Wa = 3000 - 2000 sin 60 = 1268 N
μ = 2000 / (1/2 * 1268) = 3.15 (seems to be very large, usually < 1)
