4.
Here is an equation for a spring-mass system: r" + 4x' + 5x = 0.
(a) What are the interpretations of the “ 4 "and the "5 " ?
(b) Find the general solution.
(c) Give a rough sketch of the solution to the equation using the initial values a(0)
-1, a (0) = -1. (You do not need to solve the IVP to do this, so do not solve the IVP.)
(d) Classify the type of damping this system exhibits. Explain.
