On a winter day in Maine, a warehouse worker is shoving boxes up a rough plank inclined at an angle above the horizontal. The plank is partially covered with ice, with more ice near the bottom of the plank than near the top, so that the coefficient of friction increases with the distance x along the

A flat piece of glass covers the top of a vertical cylinder that is completely filled with water. If a ray of light traveling in the glass is incident on the interface with the water at an angle of ua = 36.2, the ray refracted into the water makes an angle of 49.8o with the normal to the interface. W
