This is just algebra, but isn't simple...

#### Explanation:

Due to conservation of energy,

So

So

Or 2g.h = v^2

If we say v = h then substitute that into the previous equation,

So dividing both sides by h get us

2g = h

That means if we drop an object of any mass from 19.82 m it will hit the ground at 19.82 m/s.
