It would be water because if you freeze it than you will still be able to see it and if you boil it than you will be able to see it disappear.
I would assume air resistance is negligible and so the acceleration of the package would be approximately 9.81 m/s².
Taking downwards as positive, use v²=u²+2as.
v²=(-2)²+2(9.81)(14)
v=16.7 m/s
You go back and review Newton's laws of motion, especially #1 .
Definitely #1 .
