Enter your 3-digit class identification number:

Enter the last 4 digits of your BYU ID:

Did you carefully complete the reading assignment?
yes no

A general solution to equation 1.11 in the reading is x(t) = Aeiωt, where A is complex in general. Plug this general solution into equation 1.11. Explicitly write down your solution, separate the real parts from the imaginary parts. What do you find? How does your answer make sense, given the fact that friction is at work here?

If you plotted (the real part) of your solution to the previous question, what would it look like? How can there still be a frequency in the problem (there is, how does that work?)

Was there anything that you didn't understand in the reading assignment? If so, explain.
