An experiment that can be used to measure velocity of a bullet is to have two cardboard disks attached to a rotating shaft some distance apart and to measure the angular seperation of the holes made by the bullet. In such an experiment, two cardboard disks are placed 0.534 m apart on a shaft that is rotating at 3000 rpm. The bullet is fired parallel to the axis and the angular seperation of the holes is measured to be 22.0". What is the speed of the bullet?
