free fall equations ...Sky diver Felix :) need some help please
hi :)
OK..i tried to use the equations below to evaluate the distance or the time at which felix will reach the speed of sound ...but i failed ..i need some help:
here what i did:
first i neglect the air resistance , but the result was unreasonable so i used these:
i assumed that :
m=weight of felix=70 kg
h=the height=36000 m
k=air resistance=0.24 >> i think "k" during the falling and by the time will be increased to 70
the result was :
t=2.7*10^56 sec :0
v=53 m/s :(
i don't know what i miss here ! so if someone will help me i will be so tankful ..
