I will be glad to critique your work. We are not a homework performing service. Here are some comments to get you started.
a) gx = GM/R^2, where R is the planet's radius. G was explained in one of my previous answers.
You won't need to know the distance from the sun until you get to e) and f)
Based on the following data about planet X (which orbits around the Sun):
Planet X's distance from Sun = 3.6*1012 m
Planet X's radius = 2*106 m
Planet X's mass = 8.2*1022 kg
a.) Find gx, the size of the acceleration due to gravity on the surface of Planet X. m/s2
b.) What is the weight of a 10 kg mass on the surface of Planet X? N
(How does this compare to its weight on Earth?)
c.) How long would it take for a ball dropped from a height of 8 m to hit the ground? s
(How does this compare to the time it would take on Earth?)
d.) At 3 of Planet X's radii above the planet's surface, what is gx? m/s2
e.) Find the orbital speed of Planet X around the Sun. m/s
f.) How long is a year on Planet X? Express your answers in both seconds and Earth years:
s
Earth years
