Position Graph:
 
Velocity Graph:
 


 
Analysis:
 
The slope of the position graph equals velocity. The velocity of the ball before contact with the head is -22.97 m/s because the ball is slowing down and that is the slope of the position graph. Acceleration equals the slope of the velocity graph. The slope of the velocity graph equals 27.7 so the acceleration of the ball before contact with the head is 27.7m/s/s.



Ball After contact with head:
Position Graph:

Velocity Graph:
 

Analysis:

 The slope of the position graph equals velocity so the velocity of the ball after contact with the head 32.57 m/s. Acceleration of the ball after contact with the head is 30.81m/s/s which is the slope of the velocity graph.
 

Velocity of Head moving towards ball:
Position Graph:


Velocity Graph:


Analysis:

 
Since the slope of the position graph is velocity, the velocity of the head before contact with the ball is 4.591 m/s. Since acceleration is the slope of the velocity graph, the acceleration of the head before contact with the ball is 84.03 m/s/s.
