Assignment:
A bullet is shot through two cardboard disks attached a distance apart to a shaft turning with a rotational period , as shown.
v
a.) Derive a formula for the bullet speed in terms of D , T , and a measured angle Θ between the position of the hole in the first disk and that of the hole in the second. If required, use Π , not its numeric equivalent. Both of the holes lie at the same radial distance from the shaft Θ measures the angular displacement between the two holes; for instance, Θ =0 means that the holes are in a line and Θ =Π 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.
