![]() ![]() First, divide the length of all the segments \(D\) by the number of segments \(N\) to get the length a single segment \(d\), and propagate uncertainty. The units begin are a little wonky right now, though - "segments per second squared." time graph, the quantity measured was acceleration, which should be acceleration due to gravity. Take your five slopes, take an average, and calculate the uncertainty in this average.Īs the slope of a velocity vs. up to 10cm, noting the first velocity measured each time. Repeat dropping from higher distances - 4cm, 6cm, etc. Take note of the first velocity the program records (the first measurement listed on the data table at left), and record it. Take your uncertainty in height to be 2mm, which is dominated by the uncertainty in your ability to hold it at exactly 2cm, unless you think you did better than that, in which case you are welcome to make your own assessment.Īs before, click "Start Collection," wait a second, and drop the fence. Record this distance (as best you can measure it) to be the height \(h\). height above the photogate dropped.īegin by holding the plastic such that the bottom of the lowest black segment is about 2cm above the top of the photogate. We will hold the striped plastic some distance above the photogate, drop it, and look at the first velocity measured vs. Now, we will take a different set of measurements. Part II: Measuring \(g\) Using Drops from Varying Height Repeat the process (take data, check that it looks good, fit) for four more drops. ![]() Record the slope of this line, and then click the "x" of the little "fit" box to close it. Click "Analyze->Linear Fit" and it will output a fit with a slope. (I.e., if it dropped smoothly, all of your data if it bounced back in sight of the photogate, only the data before the bounce). time plot as follows: highlight the data on the plot in the region where it looks like a straight line. (You may want to take a screenshot for later reference as well.)įit a best fit line to your velocity vs. If the data looks OK, then make a quick sketch of what they look like on the provided sketching paper. Also do so if you have fewer than three total velocity measurements (look to the table on the left to see how many data points you have). If there is a kink in the plot somewhere (it does not look how you expect), if it hit the photogate, or if it rotated significantly as it dropped, take the data again (click "Start Collection" and drop it again). time plot, all with distance units of "segments" (pairs of black/white stripes). Once it is through, press "Stop Collection." You should see some data and three plots: a position vs. Make sure the fence drops straight through and does not rotate (be careful how you drop it), and also that it does not hit the photogate on the way down. Press "Start Collection," wait a second for it to register, and when it actually begins collecting data, drop the fence through. Make sure that the photogate starts out unblocked, so you are holding it high enough. Hold the fence just above the photogate, oriented so that the black and white stripes will go across the beam and block it (i.e., in the plane perpendicular to the laser beam). It may be convenient to put a chair underneath to catch the picket fence (but low enough so that the fence passes all the way through and does not bounce back "in sight" of the photogate). Make sure the photogate is mounted over the floor such that the striped plastic can fall through it when dropped. 1Īt this point, you should be confronted with a screen with three plots on the right and a data table on the left. In the window that pops up, click "Connect." This should set up the photogate with the computer. Open the file "Acceleration" from the LoggerPro file folder on the computer. Turn on the lab computer and log in as "Student" (if necessary). Also record how many segments ( pairs of black and white stripes) this is as \(N\). Estimate your uncertainty in this measurement. Time Graphįirst, take your striped plastic rectangle, and measure the distance \(D\) between the bottom of the lowest black stripe and the bottom of the highest black stripe.

![]() ![]() Hallmark is revealed to be in league with Foss, and tries to kidnap Tyler, but fails. Hallmark finally makes his way inside and meets Darren, who explains where the rest of the bombs are most likely located. Meanwhile, Darren manages to find and disarm a few of the bombs (as well as killing and evading a few of Foss' men), whilst Foss himself kills several hostages after the end of the first and second periods. The Secret Service and the Pittsburgh Bureau of Police team up to surround the arena and a standoff ensues. He angrily refuses, saying that he will handle this himself. ![]() ![]() Now aware of the situation, Darren finds a mobile phone in the executive offices and uses it to contact Secret Service Agent Matthew Hallmark Hallmark advises Darren to stand by while the agents take charge. Afterward, Darren asks for a security guard's help, but the guard is another terrorist in disguise and reveals their criminal operation before being killed by Darren. Carla is about to kill Darren, but he evades her attacks in a fight and kills her. Not wanting his son to go missing, Darren orders Tyler to stay in his seat while he goes searching for Emily. Carla places Emily in the suite with the other hostages about to be executed. A spat between brother and sister causes Emily to run off before getting kidnapped by Carla, the sole female member of the terrorists (who is disguised as the local mascot Iceburgh after killing the original performer). Former CIA operative Joshua Foss has the arena wired with explosives, and plans to blow it up at the end of the game, while having hundreds of millions of dollars wired into several off shore accounts.ĭarren takes his son Tyler and daughter Emily to Game 7 of the Stanley Cup Finals as a birthday gift for Tyler. During the 1995 Stanley Cup Finals between the Pittsburgh Penguins and the Chicago Blackhawks (a fictional rematch of the 1992 Stanley Cup Finals), a group of terrorists take the Vice President of the United States and several other VIPs hostage in a luxury suite. Darren McCord is a French Canadian-born firefighter for the Pittsburgh Bureau of Fire now serving as the fire marshal for the Pittsburgh Civic Arena, after being unable to save a young girl from a house fire two years prior. ![]() ![]()
