Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy
the formula to use is

where m is the mass of the object and v the velocity
lets see the kinetic energy of the sprinter running

Now, the elephant must have the same kinetic energy

it works only the positive root, so the elephant must to walk to 1.4719 m/s to have the same kinetic energy.
Have a great day
