A sled weighing 53.5 N is pulled horizontally across snow so that the coefficient of kinetic friction between sled and snow is 0.100. A penguin weighing 70.5 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 be exerted on the sled before the penguin begins to slide off.

A small child is trying to push a 100 kg box across a rough surface He is applying a force of 100 N parallel to the ground. The box, however, does not budge. The coefficient of static friction between the box and the ground is 0.8. What is the magnitude of the static friction force?

A block sits on an inclined plane, which is slowly being raised. The block remains motionless until the angle the plane makes with the horizontal is 25°. At this angle, the block begins to slide down the plane. What is the coefficient of static friction between the plane and the block?
