Hey guys, I'm having some trouble with the energy topic. So the question is:
"Calculate the gravitational potential of Earth and of Mars. Then use that information to calculate the gravitational potential energy required to life yourself completely off each planet"
So I got the gravitational Potential on Earth to -62.5 MJ/kg and on Mars it is 12.7 MJ/kg. So this is the first part of the questions, I don't get how you calculate the energy required to lift my enitre mass (which is about 70kg) off each planet.
I would really appreciate it if anyone could help me out.
