Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thank you. 1. Wall-a-stick One end of a 2.00 [m] long uniform stick is placed against a vertical wall. The other end is held by a lightweight cord that makes an angle ? with the stick. The coefficient of static friction between the end of the stick and the wall is ?s = 0.530. A. What is the maximum value the ? can have if the stick is to remain in equilibrium? B. A block of the same weight as the stick is suspended on it at a distance ? from the wall as shown. Assume that ? = 16.5° in this problem. What is the minimum value of ? for which the stick will remain in equilibrium? C. When ? = 16.5°, how large must the coefficient of static friction be so that the block can be attached 0.800 [m] from the left end of the stick without causing it to slip?

Two students want to determine the coefficient of kinetic friction of leather on oak for an experiment in their physics class. They have a block wrapped in leather that weighs 2.2 kg and notice that when they pull the block with a spring scale, the maximum force it reaches before Nie block starts to move is 13 N, and after the block starts to move the scale reads 11 N. What is the coefficient of kinetic friction? a. 5.9 b. 0.51 с. 5.0 d. 0.60
