We’ve swapped out the 2kg ball for a 20kg one. It is held 200m from the surface of the Earth. What is its GPE?

Answer:

Its gravity potential energy is 39,240 J

Step-by-step explanation:

The gravity potential energy of a body on the earth's surface is the energy a body under the influence of gravity possesses by virtue of its elevation from the surface of the earth.

We can calculate the GPE using this formula


GPE=m* g * \Delta h

from the problem given, we have m= mass= 20 kg

g = gravitational constant = 9.81m/s2

height = 200m


GPE= 20 * 9.81 * 200=39240 J

Hence, Its gravity potential energy is 39,240 J
