On Earth a 50 Kg astronaut weighs 490 Newtons. a) What would she weigh if she landed on the Moon?
b) What fraction is this of her weight on Earth?
c) What would be the escape velocity of her spacecraft from the surface from the Moon?
(Assume an 800 Kg spacecraft)
d) Is that smaller or larger than her escape velocity from the surface of the Earth? By how much?
e) If the craft was much fancier and comfortable (make it 1500Kg), would the escape velocity
increase or decrease? By how much?
