![An old Biblical story tells of David, a small warrior engaged
in man-to-man combat with Goliath, a much larger adversary.
In the story, David uses a sling to increase the speed of a
projectile (in this case a rock), striking Goliath in the
forehead and killing him.
O
The type
of sling often used in such combat consists of a long
strip of cloth with a pouch halfway down its length. The rock
is positioned in the pouch, with the warrior holding both ends
of the sling. By whirling the sling in a horizontal circle, a
warrior can release one end of the sling, thereby allowing the
projectile to fly in a straight line at high speed. Historically,
warriors and hunters typically used a vertical circle, but the
circle used here is horizontal for simplicity.
In this problem, assume that the sling, when unfolded, was
roughly R = 5.54 ft in total length and that the rock weighed
a half a pound.
If David whirled the sling such that the sling was at an angle
0 = 4.73° below the horizontal, with what speed u did the
rock strike Goliath? Assume there is no air friction and that
the drop in height due to gravity is minimal.
