Consider carefully the phase plane plot of the spring-mass system given in Figure

Figure The phase plane plot of y and v

(a) What physical configuration of the spring-mass system is represented by the points where the solution curve t → (y(t), υ(t)) crosses the y-axis?

(b) What physical configuration of the spring-mass system is represented by the points where the solution curve t → (y(t), υ(t)) crosses the y-axis?

(c) What physical significance can be attached to the fact that the solution curve t → (y(t), υ(t)) spirals toward the origin with the passage of time?
