Concept

Problem: The 1.0 kg block in the figure below is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 40 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is k = 0.35.What is the acceleration of the 2.0 kg block?______m/s2

Frictional force:

f=μN

FBD for the bottom block, calling the top block A and the bottom block B:

ΣF = T fk(A on B) - fk(ground on B) = ma
