Explanation / Answer

Which has more kinetic energy: a 0.0017-kg bullet taveling at402 m/s or a 7.9 x 10^7 - kg ocean liner traveling at 15 m/s ( 29knots) ?   ocean justify your answer Energy kinetic bullet__ Kb = 0. 5 * 0.0017 * 402 * 402 =137.36 J Energy kinetic ocean liner Ko = 0.5 * 7.9 x 107 * 15 *15 = 8.88 x 109 J
