Answer:
0 km/h vertically, horizontally yet 350 km/h
Explanation:
The bundle was inside the plane, so it start a free fall movement from rest, i.e., 0km/h, but of course the speed increases with gravity, at 9,8m/s^2 over time, but since here it is asked the vertical speed at the beginning, it is 0 km/h.
Acceleration = (end speed minus beginning speed) divided by (time for the change).
