Hi everyone,
We recently were assigned a Variable Velocity Vehicle Project (VVV) in my physics class. The idea is we are supposed to create a vehicle (with 4 wheels) that:
1) That should travel 6.00m and keep moving an additional meter before stopping. In other words, it has to stop at 7 meters exactly.
2) The vehicle must make the run with 9-13 seconds and make another one between 19-23 seconds, but the instructor assigns the time that we have to make it in, so for example, he can give us 10 and 22 seconds, and our car would have to travel 7m in 10 and 22 seconds.
3) No batteries larger than 6V can be used and the total vehicle must fit within a cubic meter and any methods of propulsion except volatile fluids and animals(haha) may be used.
4) The propulsion system could be external or internal, so ramps and moursetraps would be allowed
I was thinking something around a falling mass that turns a gear and that has a string going around another gear which would turn the axel and in order to reduce or increase time, i could have 2 sets of gears, a larger one and smaller one and I could alter the height the mass falls from to adjust its length and time. Its a basic setup, but I can't really think of anything much more efficent or advanced. Any sort of tips or advice would be really appreciated.
