Question

time it took for you grab the ruler, which you can find from the distanc e it fell (you will learn about this in the next week or so) using the equation: 2d 960 cmist 5 here g980 cm/s2. If d has an uncertainty &d, determine an expression for the uncertainty in t, 6t. 5. Now compute your reaction time along with uncertainty.
Emmonal Lemeshou Measurement of Reaction time We will now perform an experiment to measure the reaction time of each person in the lab. This is a measurement which could come in handy for future labs. 1. 2. Have one of your group mates hold the top of the ruler, while you hold your fingers at the bottom of the ruler ready to catch it. Without warning your groupmate lets go of the ruler, and you catch it between your fingers as quickly as you can. Measure the distance d in cm along with uncertainty (think carefully about what errors are involved here, and come up with a good estimate for your uncertainty. t& cm 3. Explain how you estimated the uncertainty in your measurement The wid ne finge Ployed a sole tinger wec cro mecscrec). Also we didM Sİct-Gt tne theon ne rulles

    Chapter 02, Problem 45 The drawing shows a device that you can make with a piece of cardboard, which can be used to measure a person's reaction time. Hold the card at the top and suddenly drop it. Ask a friend to try to catch the card between his or her thumb and index finger. Initially, your friend's fingers must be level with the asterisks at the bottom. By noting where your friend catches the card, you can determine his...
