An old Biblical storytelsel David all warrior end in man-to-man combat with Goliath much larger verary In the story, Davides a sing to increase the speed of projectile in this one a rock striking Goliath in the forehead and killing him The type of single wed in such combat costs of a long strip of cloth with a pouch hallway down its length. The rock is positioned in the pouch with the warrior holding both ends of the sting. By whitting the sting in a horizontaleircle, a warrior con lose one end of the sing, thereby allowing the projectile to Ily in a straight line at high speed. Postorically, warriors and hunters typically wed a vertical circle, but the circle used here is horizontal for simplicity In this problem, same that the sling, when unfolded, was roughly R-5.63ft in total length and that the rock weighed a half a pound If David wirled the sling such that the sling was at an angle 0 = 5,43" below the horizontal, with what speed did the rock strike Goliath? Assume there is no air friction and that the drop in height due to gravity is minimal mph
A typical break shot in pool (the opening shot) is about 20 mph with a ball that is about half the weight of the rock in the story Considering this, what impact would a half-pound rock traveling at the calculated speed likely have on someone if it struck them in the forehead? The impact would likely cause serious injury The impact would hurt a little but would likely not cause any injury. Suppose David missed. What distance d would the rock travel before striking the ground if David released it from a height of H = 4.25 ft? Assume there is no air friction. d = ft
