To determine which object has the highest kinetic energy, we need to consider their motion and position on the ramp.
1. If both objects are released from the same height at the same time and are identical, they will both have the same initial potential energy at the starting point.
2. As they move down the ramp, this potential energy converts into kinetic energy.
3. Kinetic energy (KE) is given by the formula: \( KE = \frac{1}{2} mv^2 \), where \( m \) is mass and \( v \) is velocity.
Since both objects are identical and have been released at the same height, the kinetic energy they gain will be the same as long as they are at the same point on the ramp.
If Object 1 is in motion and Object 2 is at rest (or not yet moving), then Object 1 will have kinetic energy while Object 2 will have zero.
However, based on the choices provided, if they are both at the same position while moving, both objects have the same kinetic energy:
Therefore, the correct response is:
**Both objects have the same kinetic energy.**
