A man stands at the edge of a cliff and throws a rock
horizontally over the edge with a speed of
v0 = 15.5 m/s.
The rock leaves his hand at a height of
h = 46.0 m
above level ground at the bottom of the cliff, as shown in the
figure. Note the coordinate system in the figure, where the origin
is at the bottom of the cliff, directly below where the rock leaves
