You are a physics teacher on the first floor of a four story high school, You notice a water balloon fall past your windows in approximately a tenth of a second \( (0.1 \mathrm{~s}) \). You measure your window to be \( 1.0 \mathrm{~m} \) from the bottom of the floor with the window itself \( 1.0 \mathrm{~m} \) high. You measure another \( 4.5 \mathrm{~m} \) to the next window. Due to the way the windows open the balloon was likely dropped from the bottom of the window. Given the information you have, was the balloon most likely dropped from a student in Mrs.Filford's class on the second story, Mr. Andy's class on the third story, Or Miss Martin's class on the purth story? \( (10 / 2) \)

A water balloon is thrown horizontally at a speed of $2.00 \mathrm{~m} / \mathrm{s}$ from the roof of a building that is $6.00 \mathrm{~m}$ above the ground. At the same instant the balloon is released, a second balloon is thrown straight down at $2.00 \mathrm{~m} / \mathrm{s}$ from the same height. Determine which balloon hits the ground first and how much sooner it hits the ground than the other balloon. (Neglect any effects due to air resistance.) SSM Example $3-5$
You drop a water balloon straight down from your dormitory window $80.0 \mathrm{~m}$ above your friend's head. At $2.00 \mathrm{~s}$ after you drop the balloon, not realizing it has water in it your friend fires a dart from a gun, which is at the same height as his head, directly upward toward the balloon with an initial velocity of $20.0 \mathrm{~m} / \mathrm{s}$. a) How long after you drop the balloon will the dart burst the balloon? b) How long after the dart hits the balloon will your friend have to move out of the way of the falling water? Assume the balloon breaks instantaneously at the touch of the dart.
