Answer all the questions please

Velocity and Acceleration are two of the most basic forms of analysis in Biomechanics. Today we will be examining the velocity and acceleration of four subjects. The procedures will be as follows. 1. We will establish a 15 meter sprinting course. 2. Measuring out 15 meters four individuals will be posted at the 0, 5, 10 and 15 meter marks. At each of these marks individuals will monitor four stopwatches. 3. Each subject will complete a sprint trial with the appropriate starting stance. 4. After each trial times from each of the positions will be reported to a time keeper. 5. Times will be recorded on the attached data sheet.

(Explain the differences) 5) What was the average 0-15M acceleration for the each stance for each of the subjects? a. Jimmy b. Jake c. Sammy I d. Becky 6) What are some anatomical differences that might affect overall velocity between subjects? 7) Describe some of the differences you observed between the four participants. 8) Describe differences in foot action between the four participants
