free fall equations ...Sky diver Felix :) need some help please
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...
thanks andrien for the reply :)
one more quastion plz:
"v" in that equations is the frame speed
what about the "a" for the body under the force ? this is what confuse me
so v depend on x ! ... how "a" can be constant?
hi every one :)
i need a small help please ...
we have tow frames and tow observers , let suppose there is a force on an object in one of the frames , so from newton law:
"a" depend on "x" distance which is not constant in the other frame , so why they assumed that it is constant...
I am a 37 years old with a BS in physics
I decided to go for a Masters degree in Physics since it only takes about two years , i know it looks late but i love physics even though i wasn't so good in BS,
and since i want to finish it good and fast i need someone to answer these...
