Question

In Cynthia's physics class, she must turn in four lab reports. For each report, she earns extra credit if her percent error is less than 5%.

For her first lab report, she calculated the value of the acceleration due to gravity 3 times. The values she got were

9.56ms2, 9.72ms2, and 9.88ms2.

The accepted value of the acceleration due to gravity is 9.8ms2.

Which option is closest to Cynthia's percent error? (Remember, take the average of the 3 measurements before calculating the percent error.)

Answer 1

The gravitational-pull is 32.2 ft/sec^2; or in metrics: 9.81m/sec^2.

5%=.05; 9.88m/sec is the best answer.
