EE X Editing 31 Physics 105/110 Overview This experiment is suggested in OpenStax Section 2.7, as follows: A simple experiment can be done to determine your reaction time. Have a friend hold a ruler between your thumb and index finger, separated by about 1cm. Note the mark on the ruler that is right between your fingers. Have your friend drop the ruler unexpectedly, and try to catch it between your two fingers. Note the new reading on the ruler. Assuming acceleration is that due to gravity, calculate your reaction time. The experiment is simple. Focus on practicing proper measurement techniques and + presenting your data and results clearly. Equipment: . Ruler (with cm and/or mm marks) A second person to drop the ruler for you Target Audience: . Write your report so that it can be read by someone that does not understand the details of your experiment, i.e. someone who is not the professor for this course. . Show your steps and explain how you arrived at your results as if you were talking to another student at your level. You can assume that the person reading this understands the prerequisites for this class. Collaborating: You can work on this lab by yourself, or with a group IF everyone works on it together at the same time. That means all group members are present via Zoom/Google Meet (or in-person) for the entire experiment and analysis. Everyone must do the calculations, but you can check your answers and submit one result. If your name is on the report, I am assuming that you participated in, understood, and could reproduce all the work submitted here. No more than 3 students can work on the same report (and share data/results). G docs.google.com C G How far would you travel in a car on the highway if the ti...

Student Name(S) Lab Report #XC: Reaction Time (Make-up) Physics 105/110 Using the overview as a guide, carry out the experiment and write a step-by-step procedure. Write what you actually do, even if it is slightly different from the instructions. Explain the reasons you set up the experiment this way. (This can be brief - I've only done this lab once before, so I don't know if you will run into any problems or need to modify it.) Do at least three trials. If you're in a group, each do one trial yourself. Experiment Procedure 3 N . G docs.google.com C G How far would you travel in a car on the highway if the ti...

(1) Give the variable name and value/units of the two kinematic quantities you measured in the experiment. (These are known quantities.) (2) There are two other variables you know. Please list the variable and its value/units. . Hint 1: The ruler starts at rest. Which quantity does this describe? + . Hint 2: Since you can ignore air resistance, the ruler is in "free fall". Which quantity does this describe? Don't forget to give the value/units of each known quantity. (3) Given the research problem in the overview, what is the unknown quantity? (Just give the variable name for now. You will calculate the value later.) (4) Which kinematic equation relates the knowns to the unknowns? (5) Use that equation to solve for the unknown.

(For example, acceleration would be a =- 9.80 m/s .) (7) Using your average as the standard value, calculate the random error for each trial. (This is a partial example.

What does it mean if the percent error is negative? Conclusion (See lab report guidelines from our regular labs for what to include.)
