I have a test coming up and I want to be able to understand the following problem:

I attached an image.

The large crate has a mass of 4kg and the smaller crate has a mass of 2kg. The coefficient of kinetic friction between each crate and the wooden table is 0.1. A hanging weight of mass 1 kg causes both crates to accelerate to the right. What's the acceleration of the block and the tension T1 and T2 in strings A and B??

My attempt:

I think I would have to set up three different equations to find acceleration?

Mass 1:

T-0.1=4a

Mass 2:

2mg+T1+T2=2mg

Mass 3:

T-1g=-1a

Can anyone help me out, please. Thanks!
