DQuestion 111 ptsAn object has a mass of 12 kg. Assume the acceleration due to gravity is 10 m/s². If it is lifted to aheight of 20 m, what is its gravitational potential energy?2400 JoulesO 2400 NewtonsO 200 JoulesO 120 Newtons

Answer 1

Given:

• Mass, m = 12 kg

,

• Acceleration due to gravity, g = 10 m/s²

,

• Height, h = 20 m

Let's find the gravitational potential energy.

To find the gravitational potential energy, apply the formula:

`GPE=m*g*h`

Where GPE is the gravitational potential energy.

Thus, we have:

`\begin{gathered} GPE=12*10*20 \\ \\ GPE=2400\text{ J} \end{gathered}`

Therefore, the gravitational potential energy is 2400 Joules.
