Labels:text | screenshot | font | document OCR: b. Find the distance between the satellite and the tracking station at 12:03 p.m. Solution: Computing angle [ gives 6 = 3 min 120 min 360º = 90 By the law of cosines, x2 = (6400)2 + (8000) - 2(6400)(8000) cos 9º = (40.96 +64 - 101.14) x 106 km2 = 3.82 x106 km2 x =1.96 x 103 = 2.0 x103 km. We have found that the distance between the satellite and the tracking station is 2000 km (to two significant figures) at 12:03 p.m. (See next card.)
