Hey, just started M1 mechanics and to be honest I'm finding it pretty difficult right now. I'm stuck on this question and have no idea on how to get to an answer.
The question:
A body falls from the top of a tower. During the last second of its motion is falls (7/16) of the whole distance. Show that the time taken for the descent is independent of the value g, and find the height of the tower in terms of g.
The answers: time 4s and height 8g metres
I have no idea how to do this so I would be very grateful for an explanation!
