Question

Raw Data Formula provided by instructor Formula that needs to be entered Open Response area 4 Prelab 3 the velocity and acceleration. For this prelab we will be using our average velocity and average acceleration formulae to complete these calculations 9 For Questions 1-3, Two different groups are measuring the SAME cart travelling with a constant velocity on a straight track. Table 1 and Table 2 represent the data collected 10 Table 1 Average Acceleration: . Use the standard "Kinematics Equations" for velocity and acceleration to find these values for each time step in Table 1 and Table 2 as well as their average and uncertainty. Definitely take advantage of Excel's "Copy" and "Paste" functions so you only need to type equations once or twice. Give special attention to the cells on the edge of the data set. 12 Average Velocity 13 Velocity Uncertaint 14 15 16 17 18 19 20 21 Acceleration Uncertaint 11.85 26.1 41.375 53.45 63.8 76.925 2. Use proper rounding techniques to report the velocity and acceleration of the cart for each data table. (Note, because the data updates every time you edit this sheet, the instructor is aware that there might be a slight mismatch between your reported value and data showing at the time of submission.) 105.425 121.2 134.35 143.075 160 173.55 184.55 198.825 208.85 223.475 Table 1: Velocity- Table 2: Velocity - Table 1: Acceleration 10 28 Table 2: Acceleration 3. Are your resuits consistent with the description given above: "T wo different groups are measuring the same cart travelling with constant velocity on a straight track." Explain any numerical inconsistencies that are in the data using your understanding of Uncertainty 32 18 235.125 34 252.575 Table 2 37 Average Velocity 38 velocity uncertaint 39 Average Acceleration Acceleration Uncertaint 41 0.595 1.84 2.26 5.005 5.075 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 4. Compare and contrast the uncertainties measured by these two groups e aroup to get more precise data than another?
