During operation a 500-kg press machine is subject to an impulse of magnitude
5000 N
s. The machine is mounted on an elastic foundation that can be modeled
as a spring of stiffness 8 � 105 N/m in parallel with a viscous damper of damping
coefficient 6000 N
s/m. What is the maximum displacement of the press after the
impulse is applied. Assume the press is at rest when the impulse is applied.
