A ball bearing is dropped from rest at point A. At the instant it passes mark 3.5m below A, another ball bearing is realeased from rest from a position of 4.5m below A. At what time after its release will the second ball bearing be overtaken by the first?(adsbygoogle = window.adsbygoogle || []).push({});

How far does the second ball bearing fall in that time?

I know i have 2 distances and it starts at rest so it doesn't have an intial velocity i also know all falling objects have an acceleration of -9.8 so i used the formula d=1/2a(t)^2 and i used 3.5 for d -9.8 for a and t is my unknown so what am i doing wrong?
