A hard algebra question

[edugatei56]

For a couple of reasons I want to know this.

I want to know what the Terminal Velocity is for a 20ft (6.06m) Shipping Container (Empty), if it were to of been dropped from lets say a helicopter, no high limit, it just needs to reach terminal velocity before it hits the group

What would the acceleration be

What would the Vertical Velocity be

How long (distance/time) would it take for it to reach terminal velocity

The sheer amount of power it would have when it hits with the groud.

It is impossible to answer that without knowing what air resistance the box has. Of course, gravity gives the box a constant acceleration of 9.81 m/s^2. If that were the only force the box would just keep increasing its speed. In order to have a limiting "terminal velocity" the box would have to have a resisting, upward force equal to the force of gravity. That would depend on things like the shape of the box.
