Question

Newton's Law of motion problem the question is in the picture.

Answer 1

I already know a,b,c,e

Answer 2

my problem is D and F broke the friction. So the acceleration of them is not 0 anymore so how do I get the acceleration of D and F

Answer 3

A,B,C,E force is not enough to broke the static friction so the acceleration is 0 right? And D and F is enough to broke the friction so I have to get the acceleartion of it (which I don't know how to)

Answer 4

find the resultant force first
