Concept $2-$ Equilibrium for tipping

$[$P$4]$ A uniform crate has a mass of $150$ kg $.$ If the coefficient of static friction between the crate and the floor is ${}_s=0\mathrm{.}2,$ determine the force required by the $85$ kg man to tip the crate. $($Do not consider slipping$).$ The coefficient of static friction between his shoes and the floor is ${}_s^{\text{'}}=0\mathrm{.}4.$ Assume that the man only exerts a horizontal force on the crate.
