1. The problem statement, all variables and given/known data I have been measuring the drop over varying distances of a projectile that was fired horizontally. I have measured the drop(s) of shot from the horizontal. while recording the distances to the target. 2. Relevant equations I have been told to use s=ut+1/2at^2 3. The attempt at a solution accelartion=gravity s=1/2gt^2. The suggested formula uses time, and i dont have the times recorded, is there a way round or do i need time?
