A machine of mass 20 kg is mounted on a spring and a dashpot as shown in the figure. The total spring stiffness is 10 N/mm and the total damping is 0.15 Ns/mm. If the system is initially at rest and a velocity of 100 mm/sec is imparted to the mass, the determine

(i) displacement and velocity of mass as a function of time, and

(ii) displacement and velocity at time equal to one second

Please correct wherever i am wrong. I have calculated the value of displacement equation, then from there we can easily find the velocity.
