The drawing (see attachment) 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 0.24 rad. From these data determine the speed of the bullet.© BrainMass Inc. brainmass.com March 21, 2019, 4:08 pm ad1c9bdddf
