Question
A person stands on the edge of a cliff. She throws three identical rocks with the
same speed. Rock X is thrown vertically upward, rock Y is thrown horizontally,
and rock Z is thrown vertically downward. Assuming the elevation loss of the
three rocks is the same (the base of the cliff is flat), which rock hits the ground
with the highest speed?
Rock Z
Rock Y
They all hit the ground with the same speed.

Rock Z Rock Y They all hit the ground with the same speed.
A person drops one rock from rest and it falls 100 meters down a cliff before
hitting the ground. The person then throws an identical rock downward. The
amount of kinetic energy gained by the rock dropped from rest is
that of
the second rock, and the magnitude of the change in speed (between hitting the
ground and its initial speed) of the rock dropped from rest is
second rock.
