Okay, here are more details. I'm planning to design a car that travels to a destination, stops, and then launches the projectile sideways to the left relative to the car itself. The projectile launcher must use only gravitational and elastic energy, must activate after the car reaches its...

Basically, it's mounted on a car. The car and the projectile together cannot be bigger than 40 cm by 30 cm by 25 cm approximately. I don't really have an idea right now, but I've heard electronic fuses work. It has to have a high degree of accuracy.

i'm trying to build a launcher that automatically launches after a period of time. it has to launch 4m and launches a projectile weighing no more than 50g. what kind of mechanisms would i need to use? thanks!
