Physics AP - Bowling Ball Lab (#5)

Background:
After going up three stories high you reach terminal velocity.  This
is why we dropped the bowling ball from three stories.   

Problem:
Find out what the height of the building and the find your error
percentage.

Procedure:
Drop a bowling ball out of the third story window.  Have two people
time the drop.  Do this four times.  Then take the average of the
times.  From that calculate height of the building.

Data:  

Ball #    time           Time average           Percentage error
1         1.42s1.39s     Bowling ball1.42s      Bowling ball25.2%

4         1.44s1.63s		

Conclusion/Analysis:
The height of the building according to the bowling ball is 9.88m and
the height of the building is 13.1m.  The percentage is 25.3%
according to bowling ball, and according to the video camera is .76%.
The timers where not accurate or the dropper weren't accurate.
