An astronaut weighs 125 lbs on the surface of the Earth. What would she weigh in lbs if she is resting in the space shuttle that is in a stable orbit 200 miles above the surface of the Earth.

Respuesta :

Answer:

weight of astronaut  [tex]F_2 = 113.38 lb[/tex]

Explanation:

Given data:

astronaut weight is = 125 lbs

distance of shuttle from  surface of earth is 200 mils

we know that [tex]F = G \frac{m_1 m_2}{r^2}[/tex]

where G, m_1, m_2 are constant value, so we have

[tex]\frac{F_1}{F_2} = \frac{r_2^2}{r_1^2}[/tex]

radius of earth is 4000 miles

where r_2 = 4000 + 200 = 4200 miles

[tex]\frac{125}{F_2} = \frac{4200^2}{4000^2}[/tex]

[tex]F_2 = 113.38 lb[/tex]
