The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance
87 cm apart on the same axle. from the
angular displacement of 21.6â—¦
of the two bullet holes in the disks and the rotational speed
537 rev/min of the disks, we can determine
the speed of the bullet.
what is the speed of the bullet?
answer in units of m/s.
