A wildlife keeper is trying to catch an escaping rabbit. Who has the greater kinetic energy, the rabbit or the wildlife keeper?
Responses
The rabbit because it has less mass.
The wildlife keeper because they have a greater mass.
Neither one because they are moving at the same speed.
The wildlife keeper because they speed up and catch the rabbit.
The wildlife keeper because they have a greater mass.
The correct answer is: Neither one because they are moving at the same speed.
To determine who has the greater kinetic energy, we need to know the formula for kinetic energy.
The formula for kinetic energy is:
Kinetic Energy = 1/2 * mass * velocity^2
Kinetic energy depends on both mass and velocity.
Since the options provided do not give specific values for the mass or velocity of the rabbit and the wildlife keeper, we cannot directly compare their kinetic energies using the formula.
However, we can make some general observations:
1. If the rabbit and the wildlife keeper have the same mass but different velocities, the one with the higher velocity will have a greater kinetic energy.
2. If the rabbit and the wildlife keeper have different masses but the same velocity, the one with the greater mass will have a greater kinetic energy.
3. If the rabbit and the wildlife keeper have different masses and different velocities, we would need more information to determine who has the greater kinetic energy.
Therefore, without specific values for mass and velocity, we cannot definitively determine who has the greater kinetic energy in this scenario.
