The mass of an object at any point will remain the same( unless its velocity approaches that of light, of course )So, for the weight to reduce to half its value, the acceleration due to gravity has to reduce to half its value on earth. now, the relation between acceleration due to gravity and distance from the center of the earth is given by g = 1/R2 where R is the radius of the earth which is 6400 kms (approx) let 'h' be the height at which the weight of the rocket will be half its initial value. so, gh / g = R2 / (R+h)2 but gh = g/ 2 substituting it in the above expression yields h=2649.6 kms (approx) so, at this height, the weight of the rocket will be half its initial weight.

I don't know how to use those formulas to figure out what the speed and how high the building would be ?

Okay, thank you! I'm pretty sure I got it! What about to know how high the building is though? Sorry if you already answered that too, I am awful with this kind of stuff

Yes, this is assuming no heat is lost

Yes
