SOLUTION: Which has more kinetic energy: a 0.0013-kg bullet traveling at 399 m/s or a 7.8 x 10^7-kg ocean liner traveling at 12 m/s (23 knots)?
the ocean liner has greater kinetic energy
Question 1205989: Which has more kinetic energy: a 0.0013-kg bullet traveling at 399 m/s or a 7.8 x 10^7-kg ocean liner traveling at 12 m/s (23 knots)?
the ocean liner has greater kinetic energy
Justify your answer.
Ek-bullet = 103.48 J (this one is correct)
Ek-ocean liner = J (I cannot find the answer for this one)
The ocean liner kinetic energy is = = 5616000000 joules.
Now compare these two numbers, 103.48 Joules and 5616000000 joules, and decide which is greater.
