Help on Mousetrap Car !!! Hello, good afternoon. I would ask you for the help of my work in physics. As you well understand, I'm not North American and my English is very bad. I am Brazilian and I ask the help of you using the Google translator. Well, as I was talking to you, I have to develop a MouseTrap Car. And I have no idea of how to begin making such a car. I have to mount a racing car, where the most time wins. I would you please help me to develop this project, because we do not understand anything about this. I hope that with the help of you I can mount an optimal car, and can learn the subject. Do not hesitate to give aid ... Good afternoon again, and thank you very much.
