speed challenge lab d÷t\nget ready!\nstep 1: gather your materials!\neach team needs 2 timers, 1 meterstick, 1 roll of masking tape, and 1 marker.\nstep 2: create your “race” track!\nfind 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.\nstep 3: go for it!\neach 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.\nnote: speed walking is going as fast as you can without jogging or running!\ncollect that data!\nrecord 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!\ntask distance time speed\nhopping 5 m 4.02\n10 m 6.72\nwalking backwards 5 m 4.39\n10 m 10.03\nwalking regular 5 m 3.47\n10 m 7.61\nspeed walking 5 m 3.05\n10 m 5.45
Answer
Explanation:
Step1: Recall speed formula
The formula for speed is $v=\frac{d}{t}$, where $v$ is speed, $d$ is distance and $t$ is time.
Step2: Calculate speed for hopping 5m
For hopping over a distance $d = 5$m and time $t=4.02$s, $v=\frac{5}{4.02}\approx1.24$m/s.
Step3: Calculate speed for hopping 10m
For hopping over a distance $d = 10$m and time $t = 6.72$s, $v=\frac{10}{6.72}\approx1.49$m/s.
Step4: Calculate speed for walking backwards 5m
For walking backwards over a distance $d = 5$m and time $t=4.39$s, $v=\frac{5}{4.39}\approx1.14$m/s.
Step5: Calculate speed for walking backwards 10m
For walking backwards over a distance $d = 10$m and time $t = 10.03$s, $v=\frac{10}{10.03}\approx0.99$m/s.
Step6: Calculate speed for regular walking 5m
For regular - walking over a distance $d = 5$m and time $t=3.47$s, $v=\frac{5}{3.47}\approx1.44$m/s.
Step7: Calculate speed for regular walking 10m
For regular - walking over a distance $d = 10$m and time $t = 7.61$s, $v=\frac{10}{7.61}\approx1.31$m/s.
Step8: Calculate speed for speed - walking 5m
For speed - walking over a distance $d = 5$m and time $t=3.05$s, $v=\frac{5}{3.05}\approx1.64$m/s.
Step9: Calculate speed for speed - walking 10m
For speed - walking over a distance $d = 10$m and time $t = 5.45$s, $v=\frac{10}{5.45}\approx1.83$m/s.
Answer:
| Task | Distance | Time | Speed |
|---|---|---|---|
| Hopping | 5 m | 4.02 s | 1.24 m/s |
| Hopping | 10 m | 6.72 s | 1.49 m/s |
| Walking Backwards | 5 m | 4.39 s | 1.14 m/s |
| Walking Backwards | 10 m | 10.03 s | 0.99 m/s |
| Walking Regular | 5 m | 3.47 s | 1.44 m/s |
| Walking Regular | 10 m | 7.61 s | 1.31 m/s |
| Speed Walking | 5 m | 3.05 s | 1.64 m/s |
| Speed Walking | 10 m | 5.45 s | 1.83 m/s |
