HELP PLEASE!
I have to create an object that will travel a straight, horizontal zipline of 7.4 meters, and then travel back .4 meters to the starting point.. The object has to be all mechanical (no electric power source) and can't weigh more than 2 kg. It also has to be pretty cheap ($50) to make/acquire. I don't have many ideas at the moment, except maybe using a balloon to propel it for one way. I don't know how I can make sure the object travels back to the starting point. I was thinking of using a spring to make it bounce back when it hits the wall after the 7.4 meter mark, but I don't think the spring will provide enough force for it to come all the way back. The object also has to be able to carry a set amount of weight on it for maximum points achieved.
Any help, ideas will be much appreciated! Thanks in advance.
