While standing on top of a 220. m tall building, you see Iron Man flying straight down toward the ground at a speed of 30.0 m/s. Just as he passes you, you drop a can of Dr Pepper off the roof. How fast is the can going when it passes Iron Man?

Answer 1

I hate these busy work problems.
the man at 30 and the falling can will have gone the same distance, solve for the time that happens
30*t=gt^2
then, the velocity at that point in time: vf=g*t

Answer 2

i dont understand
