The speed of a moving bullet can be deter
mined by allowing the bullet to pass through
two rotating paper disks mounted a distance
94 cm apart on the same axle. From the
angular displacement 48.6◦ of the two bul
let holes in the disks and the rotational speed
1156 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.
