A sled weighing $58\mathrm{.}0$ N is pulled horizontally across snow so that the coefficient of kinetic friction between sled and snow is $0\mathrm{.}100.$ A penguin weighing $73\mathrm{.}5$ N rides on the sled, as in the figure below. If the coefficient of static friction between penguin and sled is $0\mathrm{.}700,$ find the maximum horizontal force that can be exerted on the sled before the penguin begins to slide off.
