The speed of a moving bullet can be deter-
mined by allowing the bullet to pass through
two rotating paper disks mounted a distance
81 cm apart on the same axle. from the
angular displacement 13.7° of the two bul-
let holes in the disks and the rotational speed
432 rev/min of the disks, we can determine
the speed of the bullet.
