In an experiment to measure acceleration g due to gravity, two values, 9.95m/s^2 and 9.82 m/s^2, are determined. find: (a) the value of g for this experiment (b) percent error of their mean

Part a)

g = 9.885 m/s/s

Part b)

error = 0.66 %

Explanation:

Part a)

The experimental values of acceleration due to gravity is given as

now we know that the value of g is the mean value of all the readings

so we have

Part b)

error in both readings of gravity is given as

now mean error in both the readings is given as

now percentage error is given as

error = 0.66 %

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
