a variable force is exerted on a body of constant mass. the body initially at rest moves in a straight line. the following graph shows how the force varies with time. All frictional force are ignored. if the velocity of the object is 7m/s after 2 sec. the velocity after 3.4 sec will be approx. a)11.9 m/s b)20.2 m/s c)17 m/s d)28.9 m/s Please explain

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
