1. The problem statement, all variables and given/known data As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 32.0. How fast is the watermelon going when it passes Superman? 2. Relevant equations Vf=Vi+at X=Vit+(1/2)at^2 3. The attempt at a solution I guess you have to figure the velocity of the watermelon first correct? But I'm not certain how to do that. And, once I figure out the watermelon's velocity how do I determine when it passes superman?
