24. Consider a box A that weighs 1.80 N, and a box B that weighs 4.00 N. Box A is placed on top of box B, and a horizontal force is applied to box A. The static coefficient of friction between the two boxes is u =0.500, and the kinetic coefficient of friction between box B and the horizontal floor is u, = 0.150. Determine the magnitude of the applied force on box A, such that both boxes are able to maintain a constant speed as they move together to the right. a. 0.87 N. Is = 0.500 box A F applied b. 2.9 N. c. 0.27 N. box B d. 0.60 N. HK = 0.150 e. 5.8 N
