In $($Figure $1),$ the man has a mass of $85$ kg

and the crate has a mass of $150$ kg

$.$ The coefficient of static friction between his shoes and the ground is $\backslash$mu s

$=0\mathrm{.}4$ and between the crate and the ground is $\backslash$mu c

$=0\mathrm{.}3.$ 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$.$
