Question:
Working with a partner, you can get an estimate of your reaction time by catching a falling meter stick. Have your partner hold the meter stick from a point near the top while you place the finger and thumb of your catching hand about an inch apart on either side of the 50 cm mark. Without giving any cues, your partner then drops the meter stick, and when you see it move, you react to catch it by closing your finger and thumb. Record the distance that the meter stick moves between the time that your partner releases it and you catch it.
a. Repeat this process several times for each partner and compute the average distance the meter stick traveled for each partner. Tabulate your results.
b. Since the distance traveled in the time t that it takes for you to react is d = 1/2 gt2, the time of travel t = √(2d/g) is Use a calculator to compute the reaction time t for each partner from the average distance d (expressed in meters). Use g = 10 m/s2. How does your average reaction time compare to your partner’s?
c. A ‘normal’ reaction time is between 0.2 and 0.25 sec. Is your reaction time close to this? If not, explain why you think your reaction time is different
