Mr. Sul is driving his car at 20 m/s along the highway for 10 seconds . He wants to pass a car up , so for the next 5 seconds he accelerates 2 m/s² .He holds this new velocity for another 10 seconds . What is his velocity ? ( Show all work )​

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

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
