Reaction Time Lab Answer Key
Lab Activity: Reaction Time
The lab report for this action must include the following:
i. The title of the lab action
2. The date the lab activity was performed
iii. The goal(s) of the lab activity
four. A clarification of the lab action (a step-by-step procedure)
5. Data collected in the lab activeness
6. Analysis of data (calculations including those used to reply the concluding question shown beneath)
vii. Determination(s) (What did you learn?)
No error analysis needed.
In this lab yous will make up one's mind a method for measuring your reaction fourth dimension and and so use this measurement to solve a motion problem. Your chore in this lab us to determine a procedure wherein you tin use a standard 12 inch ruler, a partner, and your agreement of free fall kinematics, to make up one's mind visual reaction time. In one case a methodology is chosen, brand measurements for several trials and so average the results. Record the details of this activity in your lab notebook, including your calculations. If you lot are having trouble coming up with a method, click here to see one option.
Reaction time is defined equally the amount of time that passes between the reception of a mental stimulus and the behavioral response that follows. Research has shown that, for humans around 20 years of age, average reaction time for an aural stimulus is approximately 160 ms while that for visual stimulus is approximately 190 ms.
Now that you take data on your reaction time (and your partner's), use an online reaction fourth dimension test (click here) to compare your results with those you will generate at that website. Determine the percent divergence betwixt the reaction times you measured with the ruler and those yous adamant using the online test.
Finally, employ the reaction times yous measured with the ruler to summate the answer to the following problem:
Y'all are driving downward the road in your car at 20 m/south. All of a sudden you see a deer spring out onto the route in forepart of y'all and it doesn't move. If the maximum negative acceleration for your braking system is -4.vi 1000/s2 determine the minimum distance that the deer tin be at the moment you run across information technology, and yet non be hit by your car. Echo the calculation with the boilerplate reaction fourth dimension of your partner. Please note that there are two parts to this solution, not just ane.
