The speed of a moving bullet can be deter-
mined by allowing the bullet to pass through
two rotating paper disks mounted a distance
61 cm apart on the same axle. From the
angular displacement 14° of the two bullet
holes in the disks and the rotational speed
1436 rev/min of the disks, we can determine
the speed of the bullet.
