Don't forget about the problems due on Friday.

As I mentioned in my emailed hints, try not panic when starting the problems. Too often people read the problem and exclaim "But, I don't know the plane's mass?!?! How can I do this problem?"

Try not to psyche yourself out. Too often people get lost among the trees and fail to see the forest (or even notice that there is a cleared path behind them). Take a deep breath and work through the problem in small steps. DON'T EXPECT TO BE ABLE TO SOLVE THE PROBLEM IN A SINGLE STEP. You may not know exactly where you're going, but that's why we use the problem solving algorithm. Have faith in the physics.

 

Today, we'll continue to examine energy but with a new point of view.
