Irina standing on the edge of a cliff throws a stone at 40 degree angle above the horizontal with an initial speed of 10.0 m/s. the instant before the stone hits the ground below, it is traveling at a speed of 37 m/s. if irina were to throw the other rock at 40 degree angle below the horizontal from the cliff instead, with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground? ignore any effects of air resistance.
Answers: 3
Above horizontal 
below horizontal

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
