A stone dropped from the roof of a building hits the ground traveling at speed 19.4 m s-1 . How tall is the building, in m?

is the final velocity 0? or what do you calculate first? to get s
thanks in advance

The initial velocity is zero, you are given the final velocity. What equations do you have that include your givens and the distance of the fall.
 
relativistic motion

does anyone know the formula for v using the relativistic mass equation

i get v= the sqroot of(c^2- (restmass^2*c^2)/m^2)
rearrangeing the formula
 
cheers mate
 
You would be best off to learn the basics before including non measurable (for this problem) relativistic effects.
 
Please look where do you post things. I just understood your mistake becauseI have even seenthe other post. Try being a bit carefulnext time. Anyway you have a contrasting character of not being able to solve a free fall problem and then talk about the formula whose understanding is beyond the scope of introductory physics.
 
OMG.. I tot this was a kinematics problem..?!>">!"?!">
