In this problem, assume that the sling, when unfolded, was roughly =5.75 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 =4.43∘ 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.

Suppose David missed. What distance would the rock travel before striking the ground if David released it from a height of =4.75 ft? Assume there is no air friction.
