Watermelon and Superman experiment!

  1. 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

    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?

  3. You are going to want to find out how far above the sidewalk Superman is when the Watermelon passes him.

    To do this set the equation that shows Superman's displacement (x=vt) equal to the equation for the watermelon's displacement (X=Vit+(1/2)at^2). You can do this because the displacement for both Superman and the watermelon will be equal when they are passing.
