text: The gravitational pull on the moons surface is quite low in comparison to the earth. That is while the earths gravitational pull is 9.8m/s 10newtons the moon is 0.1666667 meters per second if you compare a man who weights 100 kg on earth will weigh about 1.7007142857142857142857142857143 kgs using the 9.8m/s gravitational rule see that is very small. Also lets concider that there is no fluid resistance(resistance caused by the air molecues while moving downwards to the earths surface.)\nthen say that the astronaut dives from 20,000 feet from the sky(let see it on both senarios "earth,moon")also  \n\n20000feet= 6096meters\naccelerations\n\nearth=9.8m/s\nmoon=1.633366m/s\n\nthe speed will increase from 0m&#92;s due to the increase in speed module =a=(v-u)/t \nto find time you can use s=1/2at^2\nacceleration on moon=1.633366m/s\nv=at+u\nv=final velocity\nu=initial velocity=0;\nt=sqrt(s/1/2a)\nt=sqrt(6096/1/2*9.8)"On earth"=35.271seconds\nt=sqrt(6096/1/2*1.633366)"On the moon"=86.396seconds\nfinal acceleration on earth is\n35.271*9.8+0=345.6558m&#92;s on the earths surface\nwhile on the moon!\ngravitational acceleration on the moon is 1.633366 meters per second=about 0.167N\ninitial velocity =0;\nfinal velocity =?\ntime taken=sqrt(6096/1/2*1.633366)= 86.396seconds\n\nfinal speed=acceleration*time+initial speed\n\n141.11696=m&#92;s on the moons surface\n\nnow into feet\n1meter =3.280 839 895 feet\n141.116 96 meter = 462.982 152 231 feet&#92;second
