The speed of a moving bullet can be determined by allowing the bullet to pass through
two rotating paper disks mounted a distance
100 cm apart on the same axle. From the
angular displacement 22.9

of the two bullet holes in the disks and the rotational speed
707 rev/min of the disks, we can determine
the speed of the bullet.
