A cube of side L = 1.40 m rests on a rough floor. It is subjected to a steady horizontal pull, F, exerted a distance h = 0.82 m above the floor as shown in figure below. As F is increased, the block will either begin to slide, or begin to tip over. What must be the coefficient of static friction μs so that the block begins to slide rather than tip?
