Data Processing:
Based on the average temporal data in Tables 1 and 2, compute the following and record the
fastest runners? results in Tables 3 and 4 below:

Lab Report:
(To be completed before the next lab meeting.)
Directions:
Two additional volunteers will be needed to complete the 25 m sprint. The procedures will be
the same as above, with volunteers stationed at each 2.5 m interval to record the times. One
volunteer will run in the positive direction, and the other volunteer will move in the negative
direction. The times will be recorded for the first runner in table 5, and for the second runner in
table 6. You will then use tables 5 & 6 to complete tables 7 & 8 for your lab report. These
tables can either be filled out at the end of this document or typed up in Word or Excel. In
addition to finishing these tables, you will answer the following question.
1. During each run Identify at which interval the following occurred (2 answers each):
a. Peak velocity (positive or negative, depending on direction of running)
b. Peak acceleration
c. Peak negative acceleration
2. In order to increase your running velocity, you will need to cover a greater displacement
in a given time, or achieve the same displacement in a less amount of time. One way of
doing this is to increase your stride length, but at some point, you will not be able to
lengthen your stride anymore as your legs are not long enough. What other kinematic
variable discussed in class that will increase your running velocity?
3. If we recreated the 25-meter run for this lab, but placed a wall at the end of the 25 meters,
how would this change our results? What do you think would change about our data?
