Assume there is no air friction.d =ft An old Biblical story tells of David, a small warrior engagedin man-to-man combat with Goliath, a much larger adversary.In the story, David uses a sling to increase the speed of aprojectile (in this case a rock), striking Goliath in theforehead and killing him.OThe typeof sling often used in such combat consists of a longstrip of cloth with a pouch halfway down its length. The rockis positioned in the pouch, with the warrior holding both endsof the sling. By whirling the sling in a horizontal circle, awarrior can release one end of the sling, thereby allowing theprojectile to fly in a straight line at high speed. Historically,warriors and hunters typically used a vertical circle, but thecircle used here is horizontal for simplicity.In this problem, assume that the sling, when unfolded, wasroughly R = 5.54 ft in total length and that the rock weigheda half a pound.If David whirled the sling such that the sling was at an angle0 = 4.73° below the horizontal, with what speed u did therock strike Goliath? Assume there is no air friction and thatthe drop in height due to gravity is minimal.CAXXXMALI
