Need help checking practice problems, image included. Thanks!

2. A uniform ladder weighing 330. N is leaning against a wall. The ladder slips when the angle with the floor is 50.00. Assuming the coefficient of static friction at the wall and the floor are the same, obtain a value for us.

A ladder of length 12.0 m with a mass of 40.0 kg leans against a smooth wall. The ladder makes a 35.0o angle with the horizontal. Draw an adequate free body diagram of the ladder and determine the minimum coefficient of static friction between the ladder and the ground necessary to prevent the ladder from slipping.

A ladder leans against a wall 5 meters above the ground so a homeowner can clear his gutters of leaves from last fall.  The bottom of the ladder just begins to slip when it is 1.7 meters from the wall.  What is the coefficient of static friction between the bottom of the ladder and the ground?

A stick which is 1.51 meters long is leaned against a wall at an angle. If the coefficient of static friction between the stick and the wall and floor is 0.395, determine the furthest distance from the wall that the bottom of the stick may be placed without slipping.

A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires.  What is the normal force that the ground exerts upward on the post?
