The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distanc
e d apart on the same axle. From the angular displacement Δθ of the two bullet holes in the disks and the rotational speed of the disks, we can determine the speed v of the bullet. Find the bullet speed for the following data: d = 70 cm, ω = 850 rev/min, and Δθ = 31.0°.........The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks?
