The lab manual derived an equation to determine the projectile velocity if we fired it into a ballistic pendulum assuming the simplest approach (measuring change in height): v ⃑_1=(m+M)/m √2g∆h However, mechanically the simplest way is to measure the max angle the pendulum swings up to. Knowing the geometry, you can derive a substitution using trigonometry. Show how you would derive the substitution: ∆h=R_CM (1-cos〖θ)〗

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
