Description

85. Two paper discs planted on a common horizontal axis so that their planes are parallel and spaced at d = 30 cm apart. The discs rotate with the frequency of n = 25 s-1. Bullet flying parallel to the axis at a distance r = 12 cm from her pierced both drives. Holes in the discs are displaced relative to each other by a distance s = 5 cm apart along a circular arc. Find the average ground speed <υ> bullet between disks and estimate generated by gravity displacement of the holes in the vertical direction. The air resistance can be disregarded.
