(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball is dropped from the top of a building and falls vertically downwards. Air resistance can be neglected. After falling a distance d, the speed of the ball is v. Determine the speed of the ball (in terms of v) when it has fallen a distance of 2d.

2. Relevant equations

3. The attempt at a solution

We tried to isolate for V_{2}and d and then substitute them into each other but that didn't work. Please help!
