To determine which of the two has lower kinetic energy, we need to use the formula for kinetic energy (KE), which is given by:
\[ KE = \frac{1}{2}mv^2 \]
where \( m \) is the mass and \( v \) is the velocity of the object.
Since we don't have the velocities for the dog and the boy, we cannot calculate their kinetic energies directly. If you provide the velocities of both the dog and the boy, I can help you calculate and compare their kinetic energies.
If they are both at rest (velocity = 0), then both have zero kinetic energy.
