Calculate the height reached when a person jumps on a planet

- Orbital period

gravitational field strength

Here are 2 questions that I have tried to answer and was hoping if these are right ways to go about it?

Q1) Find the distance in meters (m) between centre of the Moon and the centre of the Earth, assuming that the Moon moves in a circular orbit with a period of 27.5 days. Take the mass of the Earth as 6.0 × 10^24 kg. Assume that the distance between the Earth and the Moon is much larger than the radii of both planets

Q2) If a person can jump a vertical height of 1.3 m on the Earth, how high could he jump (applying the same effort as on the Earth) on a planet with the same density as the Earth, but only half the radius.

Any help would be appreciated! Thanks
