Question

Newton's Law of Gravitation states that two bodies with masses M M and N N attract each other with a force F=GMNr2, F = G M N r 2 , where r r is the distance between the bodies and G 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 5.98 × 10 24 k g and is concentrated at its center. Take the radius of the Earth to be 6.37×106m 6.37 × 10 6 m and G=6.67×10−11N⋅m2/kg2.
