Edwards & Penney Example 5 Section 2.5: Switches

Edwards & Penney Example 5 Section 4.5 (2.5 customized book)
Compare current (black dotted line) with displacement of mass (blue line). Move a and b to see influence of switch u(t-a) - u(t-b). Compare two graphs for a=0 and b=1. Increase and decrease initial velocity v_0 and see how this part is damped out for a about 1. Also see how influence of v_0 remains visible and its effect if a=0.2 or say less than 0.5. Play around with s_1 and s_2.
