The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance 92 cm apart on the same axle. from the angular displacement 20.5 ◦ of the two bullet holes in the disks and the rotational speed 406 rev/min of the disks, we can determine the speed of the bullet. find the bullet speed for the following data: d = 90 cm, ? = 800 rev/min, and ? ? = 31.0
