It takes the most amount of time for the tangerine to pass through window 4, then window 5, and it takes the least amount of time for it to pass by window 6.
Work Step by Step
At the top of the arch, the tangerine is traveling the slowest. As the flight progresses, the tangerine accelerates due to gravity. If the tangerine is traveling faster, that means it takes less time for it to pass by a window. It is traveling the slowest at window 4, so it takes the most amount of time for it to pass by that window. The tangerine is traveling the fastest at window 6, so it takes the least amount of time to pass through window 6.
