Vedclass · Answer

(B) According to Kepler's second law of planetary motion,the areal velocity of a satellite remains constant. When a satellite is in an elliptical orbit,it moves faster when it is closer to the earth (at perigee) and slower when it is farther away (at apogee) to conserve angular momentum. Angular momentum $L = mvr \sin(	heta)$ is conserved. Since $L$ is constant,$v$ is inversely proportional to $r$ when the satellite is at the closest or farthest points. Therefore,the speed is greatest when the distance $r$ from the earth is minimum.

$A$ satellite revolves around the earth in an elliptical orbit. Its speed
