Focusing on the plane first:

When the package is let go, it has a Vy of V, no acceleration, so y=Vy*t

In the z direction:

a=-g

Vz=-gt

z=.5H-.5gt^2

In the x direction:

x=0

Now for the ship:

Given is Vs=Vx=U-at

x=(1/20)*H+Ut-.5at^2

y=H

z=0

Did I set these up correctly?

Where do I go from here?

The answer is V=10U

Thanks!
