  1. Part B of the question in the book asks to solve for the displacement over the time interval 0 < t < 3 seconds. Would we just use the x(t) formula from 0 to 1.5 and again from 1.5 to 3?

    1. Note that when this book asks for the displacement they aren't referring to the distance travelled (a physics book might ask for something like that) because most of the systems in this text are oscillatory. Instead when they ask for the displacement they are asking to see a plot of the position over the time interval. I provided this plot as one of the supplements.

    1. Yes, there is an error at that point. I think that is just a copy error from one line to another, it shouldn't effect the quantity calculated for A.

      Do the numbers work out differently than I reported?
