The figure represents a drop forging process. The anvil mass is $m_l=1000kg$ and the hammer mass is $m_2=200kg.$ The support stiffness is $k={10}^7\frac{N}{m}$ and the damping constant is $c=2{10}^{4}N.\frac{S}{m}.$ The anvil is at rest when the hammer is dropped from a height of $h=1m.$ Obtain the expression for the displacement of the anvil as a function of time after the impact. Do this for two values of coefficient if restitution: $($a$)e=0$ and $($b$)e=1.$The figure represents a drop forging process.
