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 ..
