Happy Halloween!

Today is Halloween, so I decided to calculate the speed of a fun sized snickers when dropped into a trick-or-treater's bag. The mass of a fun sized snickers is approximately 17 grams. The average height of a 10 year old is 138.4 cm. With this information you can either use kinematics or conservation of energy. I chose to use kinematics and used the equation.  Vf^2 = Vo^2 + 2aΔx. Assuming that the candy is dropped from rest, falls completely vertical and neglecting air resistance, the final velocity of the candy is 52.08 cm/s.
