there is a net force in the direction of motion, that is independent of the object’s velocity
there is zero net force on the object
there is a net force in the direction of motion, that depends on the object’s velocity

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
