Morphose

I am playing around here at home and was thinking about how thrust works. This is assuming we are in space...

Let's say I had a mass of 10 metric tons (including the engine) and an engine that produces 100kg of thrust (I don't know if you would refer to it in seconds, minutes, or hours). But how fast would this mass be traveling in say 1, 6, 12, 24,and 48 hrs.?

Any claculations you could give me to help explain it would be great.

I don't know how this works, but I figured if anyone could explain it to me, somebody here could.
