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
the first bump car will move
Explanation:
this is because as long as the other bumper car is coming with force, it mass changes and then , it is able to push the other one
