For an experiment, I'm launching a projectile horizontally to determine the relationship between height and range. Pretty basic stuff. But I'm having trouble coming up with an effective way to measure the range.
I was using carbon paper to leave marks on plain paper which I can then measure, but the weight of the projectile I'm using just doesn't leave a decent enough mark to be sure that it actually landed there. I'm after a way of doing this that is more reliable.
For scale, the heights are about from 40cm to 70cm, and the range is only between 1 and 2 meters.
