Incomplete question. The remaining part of the question read;
How did the potential energy of the two vehicles change? Did the potential energy of one vehicle change more than the other? Why do you think so?
Step-by-step explanation:
1. The potential energy of the two vehicles increased because we could observe that they have unlike poles moving towards the center of the magnet. So the magnet field would be repealing both toy vehicles.
2. The potential energy of the pink vehicle change more than the purple vehicle. This is evident as we notice the pink vehicle is closer to the center of the magnet than the other.
3. The reason for this is because Lucia exerts more force (potential energy) on the pink vehicle to fight the repelling effect of the magnet
