For a class assignment, I must construct a rocket-like projectile to launch in a launching tube of 2 inches in diameter and about a little less than 2 meters in length. I am given a hard-type construction paper to make the rocket and a golf ball as my "astronaut" to be put inside when launching. I can do it whatever way I want and the competition is to see who can get the most distance. The catch is that the launching tube will be at an angle of 60 degrees. My physics teacher gave a hint as to how to make the launch a success and that is to take into consideration the center of gravity so I must find a way to have the golf ball placed at the top of the rocket and have it remain there throughout the launching to achieve distance. The problem is how will I get it to stay there? I can use glue, tape, etc. Another idea is to have a conical shape rocket with the sharp point at the back end and the front the base of the cone so it can hold the ball in place and just put the nose or nozzle to cover it up. So my question is, which way is the best to go about constructing the rocket for greatest distance? How long should the body of the rocket be?
