past A gen = 04 1658 = 12т, ар vi - - - 29 ду C D = y - 24ду vi = 2gby For earth it will be vis ² / 29 Aye For moon Vim - 29m Aym ViE = Vim 2gAyt = 2-3м дум — 29 Aye 20м Лум дум = 9. ДЕ Ям Дум. 8 (2) (0.165) |ду 12•1 т |

Part B ay = Vot - I gt When astronaut returns to earth/moon than ay-o " Ozvit 2 gt² a vita Igt²

For earth te= 2vi For moon t = 200 9.8 As veza vir + 2axy a Vg 20 di vita-2ady via-2(g) ay = 2gay - vi = jagay J 219.8) (12) 215-3m/8 Putting this value of Vi in @ is te z 2(15.3) tea 3.12 seconds Now putting value of Vicin 3 tm=2(15.3) 0.1659 tu=2(15.3 a 1869 seconds sta EM-EEF 18.9-3.12 Tata 15.8 seconds answer
