For Questions 2-3, you will perform quantitative analysesusing the data from Figures and Tables.

Body position at ball contact is essential. At ball contact, the elbow should be fully extended, and the elbow and wrist should "snap" to spike the ball towards the ground.

Question 2.What is the elbow joint angle at contact (event 6)? Round your answer to the nearest degree.

Elevation Style Elbow Angle (deg): _______________

Backswing Style Elbow Angle (deg): _______________

Question 3. What is the angular velocity of the elbow from event 5 to event 6? Fill in the table using your answers from Question 2 and the provided information.

Table 3. Elbow Angular Velocity.

	Angle (degrees)	Angular Velocity (deg/sec)
Event 5	Event 6
Elevation	102
Backswing	106

For Question 4, you are putting it all together.

Question 4. Now that you have performed both qualitative and quantitative analyses, discuss which style your athlete should use and why. Be sure to address the information provided in the tables/figures and what you have calculated.

Table 1. Timing comparisons between attack styles.

	Timing between Events (seconds)
	1 to 2	2 to 3	3 to 4	4 to 5	5 to 6
Elevation	0.022	0.014	0.015	0.021	0.031
Backswing	0.021	0.020	0.022	0.021	0.028

Table 2. Velocity of the hand at ball contact.

	Velocity (m/s)
Horizontal	Vertical	Resultant
Elevation	37.29	3.55	37.59
Backswing	36.96	4.29	37.21
