​

Answer 1

Answer:

Given Data:

$mass = 50kg$

$height = 20m$

$g = 9.8m - s2$

REQUIRED;

Energy?

Explanation:

As we know potiential energy is a type of energy so according to given data we use formula o f potiential energy:

$p = mgh$

putting values;

$p = 50 \times 20 \times 9.8$

$p = 9800j$

the stone will fall with a energy of 9800j.
