With this formula for distance calculation with gravity acceleration:(adsbygoogle = window.adsbygoogle || []).push({});

distance = 1/2 × acceleration × time^2 + intial speed × time

what Initial Acceleration does an object need to touch the ground in 3secs from 7meters of heigth?

what's the formula for that?

thx
