Thanks a lot for all the answers! I don't really remember the math too well, but at least I get that it's possible for the dropped ball to return to the platform accelerating upwards at the point where the ball was dropped, and that for that to happen, it requires knowledge of the velocity of the ball when it was dropped, and that the velocity depended on the acceleration. Although, I'm confused about the t variable. Since it's how long the system has been accelerating in total, what is how long it takes for the platform to hit the ball :o?
