Question: A 2-kg block sits on a 4-kg block that is on a frictionless table (figure). The coefficients of friction between the blocks are s

A 2-kg block sits on a 4-kg block that is on a frictionless table (figure). The coefficients of friction between the blocks are µ_s = 0.3 and µ_k = 0.2.

(a) What is the maximum force F that can be applied to the 4-kg block if the 2-kg block is not to slide?

(b) If F is half this value, find the acceleration of each block and the force of friction acting on each block.
