We will have the following:
We determine both kinetic energies:
*Person:
[tex]k_p=\frac{1}{2}(60kg)(5m/s)^2\Rightarrow k_p=750J[/tex]
*Rabbit:
[tex]k_r=\frac{1}{2}(4kg)(5m/s)^2\Rightarrow k_r=50J[/tex]
So, the person has a greater kinetic energy than the rabbit. And we know it by running the calculations and seeing that the values of energy are greater for the person.
