Question

Block A in the figure (Figure 1) weighs 1.22 N and block B weighs 3.69 N . The coefficient of kinetic friction between all surfaces is 0.304.

Find the magnitude of the horizontal force F⃗  necessary to drag block B to the left at constant speed if A rests on B and moves with it (figure (a)).
