A rock
is dropped from a building and when it finally hits the ground reaches
a final velocity of 95
meters/second. If it fell at the gravity constant rate of 9.8 m/sec/sec.
How much
TIME did it take to hit the ground?
(Note: Remember that the rock starts at
a rest, which means its OV is 0 m/sec.).
