Here is the problem you were working on in class.

I suggest you DO NOT look at the solution.  Work as hard as you can.  If you are still stuck, ask questions in class.

Here is a bonus post.

I usually give a short lecture in class about this topic, but since we already touched on it – here is a link.  Read if you like.

Here is a post you might like. It is an analysis of some gravitational wells.

Yes, I know. We haven’t looked at potential energy yet. However, this does show how near the surface of the Earth the gravitational force is essentially constant. Sorry, I thought I had a post that did the same thing with forces, but I was wrong.
