To determine who has the greater kinetic energy, we need to consider the formula for kinetic energy, which is given by:
\[ KE = \frac{1}{2} mv^2 \]
where \( KE \) is kinetic energy, \( m \) is mass, and \( v \) is velocity.
- If the rabbit is moving at a high speed (let's say faster than the wildlife keeper) but has a smaller mass, its kinetic energy could be significant because of its speed.
- If the wildlife keeper has a greater mass but is moving at a slower speed, their kinetic energy could be lower compared to the rabbit's.
Without specific information about the speeds of both the rabbit and the wildlife keeper, a definitive answer cannot be given.
However, if we assume that the wildlife keeper eventually catches the rabbit, this implies that the wildlife keeper must have increased their speed to a point where they can match or exceed the speed of the rabbit. Yet, mass also plays a crucial role in kinetic energy.
Given the choices provided and without specific values, the most reasonable conclusion would be:
The wildlife keeper because they have a greater mass (assuming they are also moving at a competitive speed).
If one of the animals is significantly faster, then the kinetic energy could favor that one. If they are moving at the same speed, then yes, the wildlife keeper's mass would give them a greater kinetic energy overall. Therefore, the answer is:
The wildlife keeper because they have a greater mass.
