A sled weighing 52.0 N is pulledhorizontally across snow so that the coefficient of kinetic friction between sled and snow is 0.100. A penguin weighing72.0 N rides on the sled, as in the figure below. If the coefficient of static friction between penguin and sled is 0.700, find the maximum horizontal force that can beexerted on the sled before the penguin begins to slide off.
