I need to build a mousetrap car that goes 25ft with a coke can. In order to decrease the mass, should I use the coke can as the front wheel and sort of just contain the can from the top (maybe bending some paperclips into a semicircle and attaching it to the mousetrap. the can will go underneath the paperclips and will be able to touch the floor but won't be able to be released). Using this, the back part of the mousetrap is pushing the can (which is acting like a wheel). My concern is whether it will go further pushing the can or will it go further on four wheels?
