Sputnik I was launched into orbit around Earth in 1957
It had a perigee (the distance from the point of closest approach to the center of Earth) of 6.61 × 106 m and an apogee (the distance from the furthest point in the orbit to the center of Earth) of 7.33 × 106 m. Its mass was 83.5 kg. What was the difference in kinetic energy as it moved from perigee to apogee? The mass of Earth is 5.97 × 1024 kg and G = 6.67 x 10-11 N•m2/kg2. A) 8.27 × 107 J B) 6.44 × 107 J C) 1.93 × 108 J D) 3.50 × 108 J E) 4.94 × 108 J
