Your task is to defend the Disney Castle from attackers. You have a catapult with which you can lob a rock with a launch speed of 14.2 m/s. from the courtyard over the walls onto the attackers at an elevation of 7.20 m. below that of the courtyard. What is the speed with which the rock will hit the ground at the attacker’s camp? Note: Use the Law of Conservation of Mechanical Energy.
