Block B has mass 4.00 kg and sits at rest on a horizontal, frictionless surface. Block A has mass 2.00 kg and sits at rest on top of block B. The coefficient of static friction between the two blocks is 0.400. A horizontal force P⃗ is then applied to block A. What is the largest value P can have and the blocks move together with equal accelerations?
