This is an incompete problem statement. It is not clear what configuration you are talking about. You need to draw a diagram. Also, you should make some attempt to figure it out on your own. We don't spoon feed answers.

As @phinds says, you are making us guess at a lot of things trying to help you. So you are wanting to compress a spring to shoot a 110kg mass out at a speed of 14m/s when released? Are these going to be big animals or humans...?
