calculate the total potential energy in kj of an object whose mass is 20 kg when it is located 20 m below a datum level in a location where g=9.5 m/s^2

Respuesta :

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.
