The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance 80 cm apart on the same axle. From the angular displacement 31 0 of the two bullet holes in the disks and the rotational speed 900 rev/min of the disks, we can determine the speed of the bullet. What is the speed of the bullet? t θ ϖ = v x t = v 139.355 = A 100 m/s B. 70 m/s C 50 m/s D 120 m/s E 140 m/s
