Flywheels achieving linear motion

Right now its part of science fair project for centripetal motion but I also am doing this to really learn about flywheels... oh and eventually im going to apply it to a Battlebot

100rpm isnt enough info. my cellphone vibration motor can be geared down to 100 rpm and my truck can also run its wheels at 100rpm.
and 2 feet bar to move it 1 foot?
the lighter the "ram", the more speed it will gain. but well. less mass.
will it just be a bar? or sharpened?
andas for going into battlebots. i would just use the flywheel itself as the weapon rather than add extra stuff which will be less efficient.

nother idea... with not exactly a disk but maybe a disk with large "bars" coming out as the flywheel.. and then somthing moves the "ram" into contact with the flywheel bars. so the bars crash into the back of the ram and it flies forwards. the cool thing about this would be multiple shots.

or just friction on the edge of the flywheel touching the ram. i had a foam dartgun that worked on this priciple a long time ago. although it had 2 flywheels. on on each side of the dart.
