Hey. I'm really not good at physics and my professor only tells stories all day so I need help with these problems. Please be as descriptive as you can so I could understand the solution.

1) A woman pushes two crates across a frictionless horizontal floor. The crates mass 4kg and 20kg respectively. If the woman exerts a force of 36 N on the smaller crate, then approximately what force does the smaller crate exert on the larger crate. (The crates are next to and touching each other. I tried to draw a free body diagram but I'm confused because the answer is 30 N and i thought it was 36N)

2) There is a picture for this question that I need so I'll just describe it. Two cables, B and C, are at 60 degrees from the ceiling and are holding a 72 N weight attached to another cable A directed straight down that is holding a 150 N weight. I have to find the tension in cables A, B, anc C. I added a diagram that I made from paint but i don't know if it worked. Thanks a lot.
