Calculate the increase in internal kinetic energy

Reference no: EM13330860

A 4.00 x 107 kg battleship originally at rest fires a 1200 kg artillery shell horizontally with a velocity of +400 m/s.

(a) If the shell is fired straight aft, there will be negligible friction opposing the ships recoil velocity. Calculate its recoil velocity.

m/s

(b) Calculate the increase in internal kinetic energy (that is, for the ship and the shell). This is less than the energy released by the gun powder -- significant heat is generated.
