Hey, for this.. can you just plug in the different distance and see when t = 60 sec. That's 1 min after the object starts falling.

No, when I did that, I got 15 secs. So at 15 secs, the object has fallen a distance of 3600 ft. However, at exactly one min, the distance the object fell is 57,600 ft.
