Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.
Answer:
The best point of reference is the starting position of the toy car.
Explanation:
To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.
