Question

What is the kinetic energy of the ocean liner ?

Answer 1

In order to calculate the kinetic energy, we can use the formula:

`E_k=(mv^2)/(2)`

Where m is the mass in kg and v is the speed in m/s.

So, for the bullet, we have:

`E_k=(0.0014\cdot408^2)/(2)=116.5\text{ J}`

And for the liner, we have:

`E_k=(59000000\cdot12^2)/(2)=4248000000\text{ J}`

So the ocean liner has greater kinetic energy.
