Suppose Group A runs their experiment 3 times and calculates that the best estimate of the distance slid by red blocks is 15 + 3 feet. Group B runs a similar experiment 3 times and calculates that the best estimate of the distance slid by green blocks is 25 + 4 feet. Using what you learned in the above video, find the t' parameter for the comparison of the results of Groups A and B.

Sorry I just need points

In comparing of result of experiment A and B, the result of A is by 2 factors differ from experiment B.

The given parameters;

in group A, distance traveled by the red block, s = 15 ± 3 feet

in group B, distance traveled by the green block, s = 25 ±  4 feet

To find:

  • the t' parameter for comparison of the results of Groups A and B.

Since both groups performed the experiment at equal times, we assume the time for both motion = t

Also, assume the initial velocity of both blocks = 0

For group A, we set-up the equation of motion as follows;

[tex]s = v_0t + \frac{1}{2} at^2 \\\\15+ 3 = 0 + 0.5\times a_1t^2\\\\18 = 0.5a_1t^2\\\\t^2 = \frac{18}{0.5a_1} \\\\t^2 = \frac{36}{a_1}[/tex]

For group B, we set-up the equation of motion as follows;

[tex]25 + 4 = v_0t + \frac{1}{2} a_2t^2\\\\29 = 0.5\times a_2t^2\\\\t^2 = \frac{29}{0.5a_2} = \frac{58}{a_2}[/tex]

Solve the first equation and the second equation together;

[tex]\frac{36}{a_1} = \frac{58}{a_2} \\\\\frac{a_2}{a_1} = \frac{58}{36} \\\\\frac{a_2}{a_1} = 1.61[/tex]

The ratio of error margin of both experiments;

[tex]\frac{4}{3} = 1.33[/tex]

The resulting parameter for comparison;

[tex]parameter, t' = 1.33 \times 1.61 = 2.14 \approx 2.0[/tex]

Thus, in comparing of result of experiment A and B, the result of A is by 2 factors differ from experiment B.
