Question
A .01kg bullet traveling at 800m/s hits a disk with a radius of R=.1m at R/2 and leaves with a speed of 400m/s. what is the angular speed of the disk right after? (omega)
I used conservation of momentum and the rotational inertia for a disk and found omega to be 8rad/s. Am I right? and if not, what should I have done?
