1. The problem statement, all variables and given/known data A 0.5 kg wooden block is placed on top of a 1.0 kg wooden block. The coefficient of static friction between the two blocks is 0.35. The coefficient of kinetic friction between the lower block and the level table is 0.20. What is the maximum horizontal force that can be applied to the lower block without the upper block slipping? 2. Relevant equations Fnet = Ff + Fg + Fapplied Ff= Mew(Fn) 3. The attempt at a solution So I tried doing this question many different ways and couldn't figure out the answer. The answer is supposed to be 8.1N. I find that there are too many variables to solve for. Thanks for the help I really appreciate it!
