Question

An object whose mass is 251 kg is located at an elevation of 24 m above the surface of the earth. For g-9.78 ms, determine the gravitational potential energy of the object, in kJ, relative to the surface of the earth.

Answer 1

Gravitational Potential =58.914 KJ

Step-by-step explanation:

We know that

`Gravitational Potential Energy = mass* g* Height`

Given mass = 251 kg

Height= 24 m

g is acceleration due to gravity =
`9.78m/s^(2)`

Applying values in the equation we get

`Gravitational Potential Energy=251X9.78X24 Joules`

`Gravitational Potential Energy=58914.72 Joules`

`Gravitational Potential Energy =(58914.72)/(1000)KJ= 58.914KJ`
