A $\backslash (51\backslash$mathrm$\{$~kg$\},3\mathrm{.}9\backslash$mathrm$\{$~m$\}\backslash )$ uniform ladder leans against a frictionless wall. A $85\mathrm{.}4$ kg person is standing on the ladder down $1\mathrm{.}33$ m from the top of the ladder. The ladder makes an angle of $62$ degrees with the horizontal. What is the minimum coefficient of static friction between the ladder and the ground so that the ladder does not slip?$0\mathrm{.}680\mathrm{.}32$
