The drawing shows a device that can be used to measure the speed of a bullet. The device consists of two rotating discs, separated by a distance d = 0.85m and rotating with an angular speed of 95 rad/sec. The bullet first passes through the left disc and then through the right disc. It is found that the angular displacement between the two bullet holes is θ = 0.24 rad. From these data determine the speed of the bullet.
