1. The problem statement, all variables and given/known data so this is a classic problem...if you know what i mean. The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance .082m apart on the sam axle. from the angular displacement 24.9 degree of the two bullet holes in the disks and the rotational speed 819rev/min of the disks. What is the speed of the bullet. in m/s^2 2. Relevant equations 3. The attempt at a solution I try to find time from the starting point of the bullet till the second hole time=(distance*2pi)/(full revolution of the disk*the degree) then use that time and put it in the equation of x final= velocity initial*time. but didnt get it so any suggestion?
