Question: 1.) a space probe lands on a distant exoplanet which has a mass of 4.83x10^24 kg. If the space probe had a mass of 30.0kg

1.) a space probe lands on a distant exoplanet which has a mass of 4.83x10^24 kg. If the space probe had a mass of 30.0kg on earth but weighs 50.0N on the exoplanet, what is the radius of this new planet?

2.) Apollo 11 astronauts were the first people to land on the moon. What speed did the landing module need to achieve in order to escape the moon's surface for them to return home? (radius of the moon is 1.74x10^6 m, g=1.63 m/s^2)
