Answer 1

Given Gravity of moon 9 = 0.165 g ho we know that, v²-4²=2gs (sorh) Thrown vertically upwards Wtru = -2gs At maximum height vso Given: s= 12m 0-us-2(g) (12) ...6= 249 on moon: = 29. Sah = - 29m .: h= 249 2* 0.1659 h = m 24 0.3.3 h = 72.727272 --- m : 1 - 72.73 ) (Answer) total time of flight as on moon too eu t 2XU 0.1659 difference to Time tm-te = tz 24 1745 Carlos - ] to en van contas - ] tu 15.8308285 Sec .: t 15.83 sec (Answer
