Yasmin determines the velocity of a car to be 15 m/s. The accepted value for the velocity of the car is 15.6 m/s. What is Yasmins percent error?

 

Good Day....

Problem:

Yasmin determines the velocity of a car to be 15 m/s. The accepted value for the velocity of the car is 15.6 m/s. What is Yasmins percent error?

Given:

experimental value for velocity  = 15 m/s

accepted value for velocity        = 15.6 m/s

percent error     = ? unknown

Formula:

percent error = experimental value - accepted value        ×    100

                                          accepted value

Solution:

First: subtract the experimental value for velocity by accepted value for velocity

        15 m/s  -  15.6 m/s   = - 0.6 m/s

Second: Take the absolute value of your answer in step 1

            - 0.6 m/s   absolute value = 0.6 m/s

Third: Divide the answer in second step by the accepted value

                      0.6 m/s ÷ 15.6 m/s  = 0.03846

Fourth : multiple your answer in third step by 100 and add the symbol % to get the percent error

                           0.03846 × 100 = 3.846 %

Answer:

Percent error is = 3.846 %
