Question

speed challenge
name
get ready!
step 1: gather your materials!
each team needs 2 timers, 1 meterstick, 1 roll of masking tape, and 1 marker.
step 2: create your
ace\ track!
find a spot in the hallway and measure off a 10 meter race track. use three pieces of tape to mark the beginning, middle, and end of your track. mark each distance (0 m, 5 m, and 10 m) on the tape with a marker.
step 3: go for it!
each team member will need to perform the following tasks for each distance: hopping, walking backwards, walking (regular rate), and speed walking. your team will need people with timers or stopwatches at the 5 meter and 10 meter points. record the time it takes to perform each task.
note: speed walking is going as fast as you can without jogging or running!
collect that data!
record your data from the experiment in the chart, then use the information to calculate the speed for each task and distance. round answers to the nearest hundredth if needed. label your answers!

Explanation:

Step1: Recall speed formula

Speed is calculated as $\text{Speed} = \frac{\text{Distance}}{\text{Time}}$, units: m/s

Step2: Calculate Hopping (5m)

$\text{Speed} = \frac{5}{2.48} \approx 2.02$ m/s

Step3: Calculate Hopping (10m)

$\text{Speed} = \frac{10}{4.94} \approx 2.02$ m/s

Step4: Calculate Walking Backwards (5m)

$\text{Speed} = \frac{5}{4.60} \approx 1.09$ m/s

Step5: Calculate Walking Backwards (10m)

$\text{Speed} = \frac{10}{9.20} \approx 1.09$ m/s

Step6: Calculate Walking Regular (5m)

$\text{Speed} = \frac{5}{3.68} \approx 1.36$ m/s

Step7: Calculate Walking Regular (10m)

$\text{Speed} = \frac{10}{7.36} \approx 1.36$ m/s

Step8: Calculate Speed Walking (5m)

$\text{Speed} = \frac{5}{2.95} \approx 1.70$ m/s

Step9: Calculate Speed Walking (10m)

$\text{Speed} = \frac{10}{3.90} \approx 2.56$ m/s

Answer:

Task	Distance	Time	Speed (m/s)
Hopping	10 m	4.94	2.02
Walking Backwards	5 m	4.60	1.09
Walking Backwards	10 m	9.20	1.09
Walking Regular	5 m	3.68	1.36
Walking Regular	10 m	7.36	1.36
Speed Walking	5 m	2.95	1.70
Speed Walking	10 m	3.90	2.56
