while moving in, a new homeowner is pushing a box across the floor at a constant velocity. the coefficient of kinetic friction between the box and the floor is 0.41. the pushing force is directed downward at an angle beta below the horizontal. when beta is greater than a certain value, it is not possible to move the box, not matter how large the pushing foce is. find beta. this is a bonus question i got for hwk. an equation or two might help. i drew a free body diagram. the question just confuses me. thanks. /prettynerd.
