A car traveling at 35 m/s suddenly runs out of gas while driving up a 7° incline. How long will it take for the car to stop after it runs out of gas (if it doesn't use its brakes and there is no friction)? How far will it travel before it stops?

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
