XVI Board Pulled Out from under a Box A small box of mass mi is sitting on a board of mass m2 and length L (Figure 1). The board rests on a frictionless horizontal surface. The coefficient of static friction between Part A the board and the box is ls. The coefficient of kinetic friction between the board and the box is, as usual, less than ls. Find Fmin, the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the the box (which will then fall off of the opposite end of the board). Throughout the problem, use g for the magnitude of the free-fall acceleration. In the hints, use f for the magnitude Express your answer in terms of some or all of the variables ls, m1, m2, g, and L.

A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mp = 6.2 kg and the sign has a mass of mg = 17.3 kg. The length of the beam is L = 2.55 m. The sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. The angle the wire makes with the beam is 0 = 34.2°.
Provide a complete solution to each problem. 1. Two painters are carrying a uniform horizontal ladder that is 12 feet long and weighs 200 N. If one person applies an upward force equal to 85 N at one end, at what point does the other person lift? 2. A uniform ladder 10.0 m long and weighing 50.0 N rests against a smooth vertical wall. (a) If the ladder is just on the verge of slipping when it makes a with the ground, find the coefficient of static friction between the ladder and ground. (b) If the coefficient of static friction is 0.360, and the same ladder makes a angle with respect to the horizontal, how far along the length of the ladder can a 65- kg painter climb before the ladder begins to slip?
