Consider the initial value problem
modeling the motion of a spring-mass-dashpot system initially at rest and subjected to an applied force
, where the unit of force is the Newton (N). Assume that
kilograms,
kilograms per second,
Newtons per meter, and the applied force in Newtons is
{20, 0<=t<=pi/2
{0, t>pi/2
