To determine which object has a greater amount of kinetic energy, we need to consider both the mass and the velocity of each object, as kinetic energy is calculated using the formula:
\[
KE = \frac{1}{2} mv^2
\]
where \( KE \) is kinetic energy, \( m \) is mass, and \( v \) is velocity.
However, since we don't have the velocities given for either object, we can't compute the exact kinetic energies. We can discuss the weights:
- The tennis ball weighs 4 ounces, which is approximately 0.25 pounds.
- The bowling ball weighs 6 pounds.
If we assume both are moving at the same velocity, the bowling ball would have more kinetic energy simply due to its greater mass. However, if the tennis ball is moving significantly faster than the bowling ball, it could potentially have more kinetic energy despite the mass difference.
In the absence of specific speeds for each object, we cannot accurately determine which has more kinetic energy. However, assuming they are both moving at the same speed, the bowling ball will have greater kinetic energy.
If we base the answer solely on weight and assume equal velocities, the answer would be:
**b)** bowling ball.
