Main Activity- Fun question

King Richard I Plantagenet (known as the “Lionheart”) is surveying the destruction his army has caused after the Siege of Limousin, when a 15- year old soldier fires an arrow at him from the top of a battlement. The arrow weighs 0.5 kg, and is fired at -45 degrees to the horizontal, which is the same angle the shooter makes with Richard the Lionheart. The crossbow bolt strikes King Richard I, who was at ground level 40 m away from the shooter. What speed was the bolt fired with if it took 2 seconds to reach the King?
