1)The breech and barrel of a field gun have a total mass of 453.6kg. The recoil of the barrel is controlled by resistance forces from a buffer and recuperator, these forces are given by: Buffer force=71000/(s+1), recuperator force= P+ 4380s. (both are in Newtons). s is the recoil of the barrel. P is the initial force in the recuperator. Determine the value of P necessary to limit the recoil to 1m when a 110N projectile is fired with a muzzle velocity of 760m/s. 2) Equations used: p(before)=p(after) from conservation of momentum. Net force F=ma. a=v.dv/vs. 3) attempted solution and question with diagram is attached. There is also an answer at the bottom but i could not get it.
