Physics
The speed of a moving bullet can be determined 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 18 ◦
of the two bullet
holes in the disks and the rotational speed
603 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.
