Nice couch lol
and aluminum I think
Answer:
v = √[ GM / (R + 160934.4 meters) ]
Explanation:
The speed of an object in a circular orbit (in meters per second) is
v = √(GM/r)
where
G = 6.6743e-11 m³ kg⁻¹ sec⁻²
M = the sum of the masses of the planet and the satellite in kilograms
r = the radius of the circular orbit in meters
If the planet's radius, R, is 100 miles, then
v = √[ GM / (R + 160934.4 meters) ]
