A gun is so designed that, on firing, the barrel recoils against a spring. A dashpot, at the end of recoil allows the barrel to come back to its initial position within the minimum time without any oscillation. The gun barrel has a mass of 1000 kg and a recoil spring of 600 N/mm. The barrel recoils 1 m on firing. Determine the (i) initial recoil velocity of the gun barrel, and (ii) critical damping coefficient of the dashpot engaged at the end of recoil stroke.

A gun is so designed that, on firing, the barrel recoils against a spring. A
dashpot, at the end of recoil allows the barrel to come back to its initial
position within the minimum time without any oscillation. The gun barrel
has a mass of 1000 kg and a recoil spring of 600 N/mm. The barrel recoils
1 m on firing. Determine the (i) initial recoil velocity of the gun barrel, and
(ii) critical damping coefficient of the dashpot engaged at the end of recoil
stroke.
