Acceleration of block on table

Homework Statement

A 10.4 kg block sits on a frictionless horizontal table. The block is attached to a horizontal ideal string that goes over an ideal pulley and is connected to another identical 10.4 kg block that hangs freely. What is the acceleration of the block on the table? State the acceleration as a positive quantity.

Homework Equations

$$\sum$$F = ma

The Attempt at a Solution

The weight of each block is 101.92 N. I'm not sure if assuming the horizontal table is 90 degrees to the ground is of any significance.
