1. when is the mechanical energy stable? 2.a moving body exerts a constant force in the direction of its velocity. is the work of this force constant? Yes or no and why?

sorry for bad english :)​

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
