Physics AP - Throw A Ball Lab (#6)

Background:
To throw your farthest you have to release the ball at 45°. 

Problem:
Find out what angle you released the ball at, the Vi, and the maximum
height.

Procedure:
Throw the ball and have someone measure the distance where the ball
first hits the ground.  Have someone time from the throw to when the
ball hit the ground.  From that calculate angle you released the ball
at, the Vi, and the maximum height.

Data:  

    X           Y       How High
  D=41m     D=7.23m     D=7.23m
V=16.8m/s  Vi=11.9m/s  Vi=11.9m/s
 A=0m/sē    T=2.44s     Vf=0m/s
 T=2.44s   A=-9.8m/sē  A=-9.8m/sē

Conclusion/Analysis:
The angle at which I threw the ball at was 35°, the Vi was 20.6m/sē
and the maximum height was 7.23m.
