1. The problem statement, all variables and given/known data 1. The problem statement, all variables and given/known data Derive a formula for the bullet speed v in terms of D, T, and a measured angle between the position of the hole in the first disk and that of the hole in the second. If required, use [tex]\pi[/tex], not its numeric equivalent. Both of the holes lie at the same radial distance from the shaft. [tex]\theta[/tex] measures the angular displacement between the two holes; for instance, [tex]\theta[/tex]=0 means that the holes are in a line and means that when one hole is up, the other is down. Assume that the bullet must travel through the set of disks within a single revolution. A diagram of this can be found here: http://ca.geocities.com/canbball/MRB_rr_8_a.jpg 2. Relevant equations Okay so I know that v=D/t And that v = (2[tex]\pi[/tex]r)/T 3. The attempt at a solution I know that the disks rotate by 2 in time T. What I don't understand is how to express this in terms of [tex]\theta[/tex]. Any help would be greatly appreciated!
