solve f and Fmax

In (Figure 1), the man has a mass of 75 kg and the crate has a mass of
130 kg. The coefficient of static friction between his shoes and the ground is
H = 0.4 and between the crate and the ground is μ = 0.3.
Figure

Prove your answer to part A by calculating the static frictional force F between the man's shoes and the ground required to move the crate and the maximum static frictional force
Fmax which can be developed.
Express your answers in newtons to three significant figures separated by a com_ma.
F, Fmax =
VAZO vec
