Answer:
The energy in object is 3.8 Kilo Joules.
Step-by-step explanation:
We are given the following in the question:
Mass = 20 kg
Height,h = 20 m
g=9.5 m/s^2
Formula:
Potential energy =
[tex]E = Mgh[/tex]
Putting value we get,
[tex]E = 20(20)(9.5)\\E = 3800~J\\E = 3.8~KJ[/tex]
Thus, the energy in object is 3.8 Kilo Joules.
