19820 J

Explanation:

Total energy is the sum of kinetic and potential energy

Potential energy is given by mgh

Kinetic energy is given by

The combination will then be and substituting m for 100 Kg and 2 m/s for v then taking g as 9.81 while h is given as 20 m we obtain energy as

answer: what are you talking about?

explanation:
