- Homework Statement
- Newton's Law of Gravitation states that two bodies with masses M

and N

attract each other with a force where r

is the distance between the bodies and G

is the gravitational constant.

Use Newton's Law of Gravitation to compute the work (in J) required to launch a 1000-kg satellite vertically to an orbit 1000 km high. You may assume that Earth's mass is 5.98×1024kg

and is concentrated at its center. Take the radius of the Earth to be 6.37×106m

and G=6.67×10−11N⋅m^2/kg^2.

- Relevant Equations
- F = GMN/r^2, W=F*d

What I did was just sub in the numbers and convert km to m. So (6.67E-10)(1000)(5.98E24)/(1,000,000+6.37E6)^2 * (1,000,000+6.37E6) So it's just (6.67E-10)(1000)(5.98E24)/(1,000,000+6.37E6). I thought this was a straightforward problem, but it seems that it is not. What am I missing?
