From the 2. π/1800 correct angular displacement 27.4◦ of the two bul- let holes in the disks and the rotational speed 3. 1800/π 872 rev/min of the disks, we can determine the speed of the bullet. 4. 60/π ◦ v 27.4 5. π Explanation: The minute hand of a watch completes one revolution in one hour. So, we have 872 rev/min 1 revolution radians 1 hr ω = 2π 73 cm 1 hr revolution 3600 s What is the speed of the bullet π
