Final answer:
In the IPDE process, predicting that a child might chase a ball into the street is using the 'Predict' step, which involves anticipating potential hazards based on the given situation.
Explanation:
The part of the IPDE process you are using when you think a child is going to follow a ball which has rolled in front of your vehicle is 'Predict'. This step involves anticipating the potential hazards that could occur given the situation at hand. For instance, if you see a ball rolling into the street, you predict that a child might chase after it. This prediction is based on the common knowledge that children often run after their toys without being aware of potential dangers such as oncoming traffic. So, by predicting what might happen next, you are employing the second step of the IPDE process, which stands for Identify, Predict, Decide, and Execute. In this scenario, after predicting the potential danger, you would need to decide what to do to avoid an accident and then execute the appropriate action to ensure safety.
