2.  What is the primary mechanical purpose associated with a projectile.  Apply these objectives to  five of the following: a high jumper, long jumper,  a shot put, discuss, javelin, golf, soccer, passing in basketball, tennis, archery.

A.

B.

C.

D.

E.
 
 

3.  Provide examples of sports in which the relative projection height is zero, a positive value and a negative value.  Start your answer by providing a definition of these different projection heights.

Zero projection height (definition/example):
 

Positive projection height (definition/example):
 

Negative projection height (definition/example):
 

4.  What are the different types of trajectories a projectile can  experience? (Note: List and draw out the trajectory)

A.

B.

C.
 

5.  List and discuss the forces which act on a projectile.

A.
 

B.
 

6.  Sometimes in soccer and football, the objective is to keep the ball in the air as long as possible. How would you accomplish this  task?  Provide text and illustrate diagramatically.
 
 
 
 
 
 

7.  Diagrammatically, illustrate the influence of gravity on a  projectile.
 
 
 
 
 
 
 
 
 
 
 
 
 

8.  Diagrammatically, illustrate the trajectory (path) of two of the following:  a long jumper, javelin, soccer ball, or basketball.  Utilize arrows to indicate the vertical and horizontal vector (utilize velocity vectors) of the long jumper throughout the trajectory.

A.
 
 
 
 
 

B.
 
 

9. Consider the following:

1) A shot putter (Ht. 6 ft 4 inches) releases a shot at a height of 2.2 meters with  an initial (resultant) velocity of 5.0 m/s at an angle of 30  degrees to the horizontal.

A. Diagrammatically, illustrate the trajectory of the shot.
Use vectors to illustrate the vertical and horizontal velocity of the shot throughout the trajectory.
 
 
 
 
 
 

B.  Diagrammatically illustrate what projectile components you would change in order to increase  the horizontal displacement of the shot. (Consider all those components that influence the horizontal displacement of the shot)
 
 
 
 
 
 
 
 
 
 
 

2) You are at the seventh and deciding baseball game of the World  Series.  There are two outs in the bottom of the ninth and the offensive team is down by one point.  At this particular field  it is 130 meters from home plate to the center field wall.  A batter swings and hits a pitched ball with an initial velocity  of 30 m/s at an angle of 70 degrees to the horizontal.  Using your intuition and assuming  the ball was struck at a height of 0.75 meters above ground, will the batter hit a home run or pop fly? Using the above data, illustrate the trajectory of the ball. Use vectors in your illustration . (For the sake of this  question, assume that once hit, the ball is traveling exactly  straight towards center field).
