Question

You are a general in the Napoleonic wars. An enemy fort 10m tall is located 1000m from your cannon. Your cannon expert is insisting that you will get the best results at an angle of 25 above the horizontal. Your cannon is located on a hill 10m tall. You have soldiers storming the plain in front of the fort in order to storm the building once the wall has been breached And there are civilians inside that you do not want to kill. If the initial speed of the cannonball is 112 m/s will the cannonball strike the building at what height overshoot and kill the civilians inside or hit your shoulders who are storming the plain in front of the building.
