The picture below shows Peggy's new racetrack. It has different starting positions and an upside-down loop for cars to go through. She has 3 cars that she wants to try on the track: a sports car, a truck, and a jeep. 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?

Question

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

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

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

an experiment where Peggy drops each car from the same starting height and records which cars complete the loop from that height

Answer 1

To determine the best way to choose the starting position that allows every car to complete the loop, the suitable experiment would be:

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.

This experiment allows Peggy to systematically test various heights to find a height that works for all three types of cars (sports car, truck, and jeep), ensuring that she finds a starting position that guarantees each car can successfully complete the loop. By conducting multiple trials, she can also account for variability in the performance of each car.
