Answer:

Antoine Lavoisier and Johann Döbereiner

Explanation:

One of the very first attempt to classify the elements was made in 1789 by Antoine Lavoisier who grouped all the elements based on their properties into whether they are gases, metals or non metals and earths metals.

Johann Döbereiner in 1829, recognised triads of elements with similar chemical properties and showed that the properties of the element that is in the middle of other two elements can be predicted from the properties of the other two.

For this part, we can disregard the horizontal velocity because horizontal and vertical motion are INDEPENDENT.

We can used the simplified equation to solve for time:

$t = \sqrt{\frac{2h}{g}}$
