Optimizing the Launch of a Projectile to Hit a Target
Mungan, Carl E.
Physics Teacher, v55 n9 p528-529 Dec 2017
Some teenagers are exploring the outer perimeter of a castle. They notice a spy hole in its wall, across the moat a horizontal distance "x" and vertically up the wall a distance "y." They decide to throw pebbles at the hole. One girl wants to use physics to throw with the minimum speed necessary to hit the hole. What is the required launch speed "v" and launch angle ? above the horizontal?
