I'm sorry, I don't understand. Aren't any force acting on the bottom also affecting the top and vice-versa? Why is my approach incorrect?

I added the masses together because the normal force is equal to the mass of both block together, is it not? It was set equal to the force of static friction because I thought this would be the maximum force that would not move the top block. It was set equal to ma, because both block accelerate...

Homework Statement The coefficient of static friction is 0.625 between the two blocks shown. The coefficient of kinetic friction between the lower block and the floor is 0.137. Force F causes both blocks to cross a distance of 4.46m, starting from rest. What is the least amount of time in which...
