Well, kinetic energy is energy of motion, and three of these

four objects are just sitting there and not moving at all.

The tank, the car, and the boulder have no kinetic energy at all,

since they're not moving.

The fish who is swimming is the only one with any kinetic energy,

so we don't even have to calculate how much. The fish is your man.
