Calculate the gravitational potential energy of a 8.6-kg mass on the surface of the Earth. Express your answer using two significant figures.

The gravitational potential energy of the 8.6 kg mass is 5.38x10⁸ J.

Explanation:

We can find the gravitational potential energy of the mass using the following equation:                      

Where:

m: is the mass = 8.6 kg

g: is the gravity = 9.81 m/s^{2}  

h: is the height = Earth's radius = 6371 km

Hence, we have:

Therefore, the gravitational potential energy of the 8.6 kg mass is 5.38x10⁸ J.

I hope it helps you!                                                            

that would be because of both gravity and friction. so     c
