A 400g model rocket is on a cart that is rolling to the right at a speed of 4.0m/s. The rocket engine, when it is fired, exerts an 7.0 N thrust on the rocket. Your goal is to have the rocket pass through a small horizontal hoop that is 15m above the launch point.

This should work in most cases where you want to drill holes that are exactly 180 degrees apart on the boom of a Yagi antenna you are building, or for that matter, with any project that requires holes 180 degrees apart in round tubing. If you don't have a drill press or drill guide.....80 degree protractor on left....360 degree version on right. (not to scale). Now since tubing is usually a perfect 360 degree circle when viewed from the end, you want to be able to find a way to mark both sides of it for the Yagi antenna element holes we are using in this example that you want to drill.
