I am pretty new to physics so forgive me if this seems like a really dumb question.

My Physics I teacher is having us develop a solution to the question:
**You drop your laptop; what is its acceleration as it hits the ground?** 

The truth is I have no idea where to start. On top of that, the teacher wants us to include what would happen (conceptually) if the laptop lands on a corner versus one of the sides or what would happen if the laptop was dropped on concrete as opposed to a more forgiving surface.
I was hoping someone could walk me through the process.

Thank to everybody in advance.
