A student sees her physical science professor approaching on the sidewalk that runs by her dorm. She gets a water ballon and waits.When the professor is 2.0 s from being directly under her window 11 m above the sidewalk,she drops the ballon. You finish the story.

Hey, you finish the story since you already started it :)

Basically, find the time that the balloon takes to fall to the ground. What do you think would happen if the balloon took exactly 2.0 s? What if it took more time? What if it took less time?
