The cannon fires a 16-lb cannonball with an absolute velocity of 900 ft/sec at 22° to the horizontal. The combined weight of the cannon and its cart is 1932 lb. If the recoil mechanism consists of the spring of constant k = 2160 lb/ft and the damper with viscous coefficient c = 720 lb-sec/ft, determine the maximum recoil deflection Xmax (a positive number) of the cannon unit. جاد Answer: Xmax= i 900 ft/sec 22° ft
