1. The problem statement, all variables and given/known data You are an invading army who wants to launch a rock over the enemy castle’s wall. The wall is 12 meters high and there is a moat surrounding the wall which forces you to launch from a distance of 17 meters away. What angle and velocity should you shoot at in order to just clear the wall at the top of your projectile’s trajectory? 2. Relevant equations No idea. 3. The attempt at a solution I have read through the relevant chapter in my book twice now trying to find a solution or process to find the angle and velocity for a specific height, but all I can find is referring to maximum distance. I would really appreciate any help even just pointing me in the right direction! Thanks so much in advance!
