Auniform stick 1.5 m long with a total mass of 300 g is pivoted at its center. a 3.0-g bullet is shot through the stick midway between the pivot and one end the bullet approaches at 250 m/s and leaves at 140 m/s.
with what angular speed is the stick spinning after the collision?
ω= rad/s

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
