Two diamonds begin a free fall from rest from the same height, a time "delta t" apart. How long after the first diamond begins to fall will the two diamonds be a distance "d" apart? Give your answer in terms of the variables given and "g". ( Solve for t= )
Variables: "delta" t, "d", and "g"
The Attempt at a Solution
I know "g" is the gravitational constant and will have an effect on "delta" t, but I just can't figure out how to set up this equation. I know it is an form of one of the Constant-Acceleration equations, but there's like 5 of them and I don't know which one to use. Thanks in advance.
