72 J
Explanation:
Kinetic energy of an object is the energy an object has because of its motion.
Since the dog is running at the given speed , it possesses a Kinetic energy
[tex]Kinetic.Energy=\frac{1}{2}*mass*velocity^{2} \\Kinetic.Energy=\frac{1}{2}*16kg*(3ms^{-1} )^{2} \\Kinetic.Energy=72J[/tex]
