Explanation / Answer

1Given E =384400km..... orbital period= 27.3days....therefore 1)distance in meters= 384400000m......2) period of motion= 27.3×24×60×60 = 2358720sec.......... velocity = (2)(pi)R/T = =2 ×3.14×384400000/2358720 = 1023.4m/sec......4)accleration a = v2/r =(1023.4)(1023.4)/384400000 = 0.0027m/sec2
