satellite mechanics: linear and rotational momentum

I'm trying to better understand classical mechanics, and came up with a question:

Say we have a squared satellite weighting 100kg, 1 meter on each side. it has a thruster on it's side, shown in picture

thruster quickly ejects 100g of propellant with a speed of 1000m/s giving a satellite 100kg m/s of momentum. the question is how much of it will be given to rotation, and how much - to linear motion
