Problem: An innocent bystander is standing-by on the sidewalk by a building waiting for a taxi. Little Jimmy Quagmyre, the neighborhood spoiled brat and all-around obnoxious little monster, is leaning out of the third-story window holding a balloon filled with molasses. He drops the balloon onto the bystander.
Part A: How fast is the balloon traveling when it hits the bystander on the head if Jimmy is 11 m above the sidewalk and the bystander is 2-m tall?
I need proficient help in the above problem.
