1. The problem statement, all variables and given/known data a spacecraft of mass 1000kg, in an elliptical orbit about the earth, at one point its distance from earth is 1.2 x 107 meters and its velocity is 7.1 x 103 meters per sec, and the velocity vector is perpendicular to the line connecting the center of the earth to the spacecraft. Mass of earth is 6.0 x 1024 kg and radius of earth is 6.4 x 106 Find the magnitude of the angular moemntum of the spacecraft about the center of the earth 2. Relevant equations L = I [tex]\omega[/tex] L = r x p [tex]\omega[/tex] = v/r 3. The attempt at a solution ok so I know that energy and angular momentum is conserved. I know how to solve this but I just want to make sure. Do I just do this by finding the angular velocity by [tex]\omega[/tex] = v/r then multiplied by I which equals to mr2 . it sounds really weird so I just want to make sure.
