How can I build the most efficient mouse trap car to travel over 175 feet?

[Brandonian]

Hey everyone, My name is Brandon and I have been assigned a mouse trap car project for my high school engineering class.

Homework Statement

The following are the specs:
-I need it to go the maximum distance
-Must travel in a straight line
The materials supplied:
-4 ea. CD's (wheels)
-2 ea. 1/4" brass axles
-4 ea. 1/4" beveled rubber washers
-4 ea. 1/4" flast rubber washers
-4 ea. 1/4" flat steel washers
-2 ea. Balsaa wood chassis rails, 36" long max.
-1 ea. 1/8" x 3" x 12" balsa deck
-1 ea. 1/8" x 12" brass tube
-1 Small mouse trap (4.5 x 10 centimeters)
-1 Small zip tie
-Fishing line cut to any length

Homework Equations

My concern is figuring out how to build the most efficient mouse trap car to go upwards of 175 feet. In addition I am allowed to use my own materials but the ones listed above must be used. Also, the mouse trap it self can NOT be modified. Does anyone have any suggestions?

I did one when i was in SEA (Science and engineering academy) camp a few summers back. I found that if you keep the axels well lubricated and sturdy, it would be a good start. just make sure you get all of the pieces put to gether as well as you can and don't cut corners. that's the best i got, but nobody else seems to be helping
