Homework Statement
You and your friend are on top of a roof... You simply drop a balloon from rest. Your friend throws a balloon downward 2.7s later with an initial speed of 52.92m/s. They hit the ground at the same time. Neglect air resistance. How high is the apartment house?
2. The attempt at a solution
My thinking on this is that after 3.2 seconds balloon 1 has traveled 31.36m, and balloon 2 has traveled 31.36m after .5 seconds, meaning the building would be 31.36m tall, but evidently my thinking is off somewhere.
So, if anyone could explain what it is I'm doing wrong with this one, it would be much appreciated.
Thanks.
