In the lab, michelle and brian measured the acceleration of a cart rolling on an inclined track with one block under one end, and found that the acceleration was 0.482 m/s2. on another table, yasin and cameron found, with a similar setup, an acceleration of 0.718 m/s2. a. what is the percent difference between the result found by yasin and cameron, ay& c, in terms of the result of michelle and brian, am& b? b. what is the percent difference between the two results when you treat them as "equivalent"?

a)  e% = 49.0%

, b)  e% = 19.7%

Explanation:

The percentage difference is the absolute uncertainty between the value accepted by 100

               e% = Δx / x_value

a) for this case the correct accepted value is x_value = 0.482 m / s²

               Δx = 0.718 - 0.482

               Δx = 0.236 m / s²

               e% = 0.236 / 0.482 100

               e% = 48.96%

b) In this case the results of the two experiments are real and the correct value is the average

              x_value = (0.482 + 0.718) / 2

              x_value = 0.600 m / s²

              e% = (0.718 - 0.600) / 0.600 100

              e% = 19.7%
