All will have a dominant trait I can't see the following statments
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
No,because they may have more particles
To get the best possible answer. (sorry if im wrong)
