How Do You Calculate Tensions in a Dual-Block and Rope System?

[Darklink8]

Homework Statement

The figure shows two 1.0 kg blocks connected by a rope. A second rope hangs beneath the lower block. Both ropes have a mass of 250 g. The entire assembly is accelerated upward at 3m/sec^2 by force F.

What are the following tensions:

1. The tension of the top of rope 1.
2. The tention of the bottem of rope 1.
3. The tension of the top of rope 2.

Includes the following diagram

Homework Equations

Fnet = 2.5*-9.8+F
T=g(mass of all things under it)

The Attempt at a Solution

Tsub1 = (.25+.25+1)g
Tsub2 = .25g

But these answers are wrong...
