The response options (A, B, C) are missing. Please provide the complete response options for me to determine the correct answer.
Answered by GPT 3.5
Since there is no diagram or information provided about the positions or velocities of Objects 1 and 2, it is not possible to determine which object has the highest kinetic energy.
