Ok, so I came up with part an answer for the question I posted, hoping that someone can compare with me. I..this is what I did....
found the displacement of car before red light, time it takes for the car to accelerate to its velocity, after the red light, the time of the car before the red light, and the total displacement of the train (which I don't know if that can be done or not) Does this sound right? I am most definite I am missing parts? But what?
Thanks
I think you are correct, I don't see any parts you are missing.

It seems like you're working on a problem involving a car and a red light, and you're trying to find some missing parts. To verify if your approach is correct, let's break down the problem and see what additional information or steps you might need.
1. Displacement of the car before the red light: To find this, you need to know the initial position of the car and the distance from the initial position to the red light.
2. Time it takes for the car to accelerate to its velocity: This requires knowing the initial velocity of the car, the acceleration of the car, and the final desired velocity. You can calculate this time using the formula: time = (final velocity - initial velocity) / acceleration.
3. Time of the car after the red light: If the car starts moving again after the red light, you need to know how long it takes for the car to reach a specific point after the light. This would involve knowing the distance from the red light to that point and the car's acceleration.
4. Total displacement of the train: It's important to clarify if the train is related to this problem and if its displacement affects the car's motion. If it does, you need to know the initial and final positions of the train, as well as any changes in its velocity or acceleration.
Based on the information you provided, it's not clear if you have all the necessary details to solve the problem completely. Make sure you have the required values for position, velocity, acceleration, and time for both the car and the train, depending on their relevance to the problem.
