Pretend that you have taken one step on the ground and have traveled 30 cm. Now, if you were elevated by 50,000 feet from the ground and taken the same step then landed back down, would you have traveled the same distance? or did you travel further than 30 cm?

THIS IS A VERY strange question in deed. take into consideration ideal world etc .....
when you wald idealy you exert a force with a vector in the same dierection as the movement. gravity "pulls" you back and you end up with a normal step.
now gettting back to the projectile movement. ..as you may know the Ux (in the horizontalaxis) is constant.
NUT is lasts as long as the Uy allows it to do so.
meaning that the more the body is on the air the more it is travelling to the X-axis. so at 50000 ti will take the body long long time to fall threfore the X-effect will be present for many more more more second resulting to a greater distance travelled
imagine it this wya.
throw at the same angle and using the same force (= same velocity) a basevall from the 1st floor.
then do the same under the ame parameters doing so from the 15th floor. which one will be landed further than the other.
it will be the one from the the 15th floor because the Ux vector will be there for more seconds than the other.

Way further than 30 cm. It's all about vector you see.

you travel the same distance .... you only feel u travelled more from high up there .. coz everything will look smaller to u....... a good experiment would be a graph paper ..... put a dot and move it from a to point b... then put another dot and placit higher and more it .. loool its not rocket science ... its logic .... :) take care now
