First, we will need to know the formula to calculate the kinetic energy
[tex]K.E.=\frac{1}{2}\cdot m\cdot v^2[/tex]where m is the mass and v is the speed
then we will calculate the kinetic energy for each case
For the bullet
m=0.0020 kg
v=400 m/s
[tex]K.E.=\frac{1}{2}(0.0020)\cdot(400)^2=160J[/tex]for the ocean liner
m=6.4x10^7 kg
v=10 m/s
[tex]K.E.=\frac{1}{2}(6.4\times10^7)\cdot(10)^2=3200000000J=32\times10^8J[/tex]as we can see the ocean liner has more Kinetic energy.
