Please,I need help with this problem.... You are launching a 200kg projectile over the castle wall and trying to hit the keep. If the catapult holds the projectile for 2 seconds before releasing what is the average force delievered by the catapult? The keep itself is located 75 meters inside the castle wall while the catapult is 50 meters outside the castle wall. Determine the initial velocity (speed & angle with respect to the horizontal) of the projectile if it is to just clear the castle wall and impact the keep. Remember the wall is 12 meters high.
