    A battleship that is 5.85 times 10^7 kg and originally at rest fires a 1100-kg artillery shell horizontally with a velocity of 595 m/s. (a) If the shell is fired straight aft (toward the rear of the ship), there will be negligible friction opposing the ship's recoil. Calculate the recoil velocity of the ship, taking the firing direction to be the positive direction. (b) Calculate the change kinetic energy for the ship and the shell. This energy is less than...
