hi ..
any body have any idea :(
by the way this is not for home work , it just a question pop up to me and i want to solve it , but it has been moved here :)
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...
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
a=dv/dt
v=x/t
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:
f=ma
"a" depend on "x" distance which is not constant in the other frame , so why they assumed that it is constant...
another question plz::smile:
for a medium intelligent person but ready for hard work: how much time do you think it will take to get prepared?
thanks again and have a nice day
thank you so much physiker_192 for the link that was so helpful
absolutely, it was my main obstacle i will spend more time on it :rolleyes: :)
thanks again
Hello, :smile:
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...
