If each box weighs 160 lb , determine the least horizontal force P that the man must exert on the top box in order to cause motion. The coefficient of static friction between the boxes is μs = 0.80, and the coefficient of static friction between the box and the floor is μ′s = 0.25. (Figure 1) -3 ft 4.5 ft 5 ft 4.5 ft А B
Question 14 5 pts If each box weighs 120 lb, determine the horizontal force P (in units of lb) necessary to cause both boxes to tip as a single unit. The coefficient of static friction between the boxes is . -0.62, and the coefficient of static friction between the bottom box and the floor is H. -0.27. 4.5 ft 5 ft 4.5 ft
12.2) What is the smallest horizontal force, P, that the person must exert on the top box to initiate motion (slip or tip). Each box weighs 125 lb. The coefficient of static friction between the boxes is 0.5 and the coefficient of static friction between the box and the floor is 0.35.

1. A wagon weighs 12.0 lb, and the coefficient of rolling friction between the wheels and the floor is 0.140. What horizontal pull is need to keep the wagon rolling in a straight line at 2.00 ft/s? 2. A wagon weighs 50.0 N, and the coefficient of rolling friction between the wheels and the level floor is 0.150. What horizontal pull is need to keep the wagon rolling uniformly?
