Show me the steps to solve Block A in ( Figure 1 ) weighs 1 . 1 0 N , and block B weighs 3 . 5 5 N . The coefficient of kinetic friction between all surfaces is 0 . 2 9 5 . Find the magnitude of the horizontal force F ⃗ necessary to drag block B to the left at constant speed if A is held at rest ( figure ( b ) ) .
