leahmaew Posted September 11, 2012 Share Posted September 11, 2012 Leah, Katrina, Holly, Sarah 9/11/12 Speeding Lab 1.In the speeding lab, we were measuring the speed of cars to see if cars were going over the speed limit, which was 35 mph or 15.6 meters per second. The project was to come up with an experiment to find out how many cars were speeding on the road in front of our school. We needed to find a way to gather information so accurately determine the amount of cars speeding. 2. - We took a tape measure, a stop watch and used to rocks at spot markers. - We marked the beginning of the 30 meters with a rock and had one person stand there with a stop watch - We marked the end of the 30 meters with another rock and had a second person stand there, -We communicated which car we would be timing, by having the person at the beginning of the 30 meters begin the stop watch and raising their arm to let the person at the end of the 30 meters know which car. When said car passed the marked spot at the end of the 30 meters the person would raise their arm to indicate to the first person to stop the timer. -The person with the timer told the two recorders what the time was and they recorded it. -We repeated this procress for 10 different cars. - After collecting data for 10 cars we changed the tap measurement to 50 meters and did the same thing for another 10 cars. -Collected data for 10 cars 3. 4 and 5 [TABLE="width: 320"] [TR] [TD]Car#[/TD] [TD]Distance[/TD] [TD]Time[/TD] [TD="colspan: 2"]Speed (m/s)[/TD] [/TR] [TR] [TD="align: right"]1[/TD] [TD="align: right"]30[/TD] [TD="align: right"]1.8[/TD] [TD="align: right"]16.66667[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]2[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.53[/TD] [TD="align: right"]11.85771[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]3[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.09[/TD] [TD="align: right"]14.35407[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]4[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.3[/TD] [TD="align: right"]13.04348[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]5[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.64[/TD] [TD="align: right"]11.36364[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]6[/TD] [TD="align: right"]30[/TD] [TD="align: right"]1.87[/TD] [TD="align: right"]16.04278[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]7[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.09[/TD] [TD="align: right"]14.35407[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]8[/TD] [TD="align: right"]30[/TD] [TD="align: right"]3.05[/TD] [TD="align: right"]9.836066[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]9[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.4[/TD] [TD="align: right"]12.5[/TD] [TD][/TD] [/TR] [TR] [TD="align: right"]10[/TD] [TD="align: right"]30[/TD] [TD="align: right"]2.17[/TD] [TD="align: right"]13.82488[/TD] [TD][/TD] [/TR] [TR] [TD][/TD] [TD]Average[/TD] [TD="align: right"]2.294[/TD] [TD="align: right"]13.38434[/TD] [TD][/TD] [/TR] [/TABLE] Quote Link to comment Share on other sites More sharing options...
