Question

If you have a mass of 30 kilograms and you are resting on top of a hill that is 20 meters high how much energy would you have.

Answer 1

we can have 2 values one is with g taken as 10 m/s² and the second with g taken as 9.8m/s² where g is the acceleration due to gravity

when g is 10,

30kg×10m/s²×20m. using m×g×h

6000 J

when g is 9.8

30×9.8×20

4080 J
