Peggy knows that height can change how fast a car will go. Which experiment will help Peggy choose the starting position that allows every car to complete the loop?
A.
an experiment where Peggy drops each car from different starting heights multiple times and records which heights allow all three cars to complete the loop every time
B.
an experiment where Peggy drops each car from the same starting height and measures the amount of time it takes each car to complete the loop
C.
an experiment where Peggy drops each car from different starting heights multiple times and measures how far each car goes on the course after completing the loop
D.
an experiment where Peggy drops each car from the same starting height and records which cars complete the loop from that height
A. an experiment where Peggy drops each car from different starting heights multiple times and records which heights allow all three cars to complete the loop every time
A.
An experiment where Peggy drops each car from different starting heights multiple times and records which heights allow all three cars to complete the loop every time.
The correct experiment in this case would be option A - an experiment where Peggy drops each car from different starting heights multiple times and records which heights allow all three cars to complete the loop every time.
To determine the starting position that allows every car to complete the loop, Peggy needs to test different starting heights. By dropping each car from different starting heights multiple times, Peggy can observe and record which heights consistently result in all three cars successfully completing the loop. This experiment will provide the necessary data to identify the starting position that ensures every car completes the loop.
