A 4.98-kg block is placed on top of a 11.4-kg block that rests on a frictionless table. The coefficient of static friction between the two blocks is 0.500. What is the maximum horizontal force that can be applied before the 4.98-kg block begins to slip relative to the 11.4-kg block, if the force is applied to the more massive block?
I'm thinking something like Fnet = F1 + F2 + F3 but I'm not really sure..
The Attempt at a Solution
First I just assumed that the tension would be equal since the mass is constant but of course it's not that easy..
I found acceleration to be 1.108N/Kg by taking the tension and diving by the mass 2 and 3. That seems to be the only thing I can do with that information and I don't know what to do with that accerlation. Could I times it by say mass 1+mass 2 to get the tension?
Thanks in advance!
