34. A battleship that is 6.00x107kg and is originally at rest fires a 1100-kg artillery shell horizontally with a velocity
of 575 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 its recoil velocity. (b) Calculate the increase in internal kinetic energy (that is, for the ship
thon the eneray released by the gun powder-significant heat transfer occurs.
