where / is the moment of inertia 0 of the bullet about the axis, v is its velocity, and b is its distance from the axis just before it hits the target, Fig. 123. The bullet is supposed to hit the target normally, when the latter is in the equilibriumposition, and to be imbedded in it. The angular… … Fig. 123. (/ + /)o. 1,1 + 1 V= 0 —;i—CO. (1) If we suppose the energy lost during the impact to be negli-gible the kinetic energy of rotation just after the bullet hitsthe target equals the potential energy of the system at itsposition of maximum angular displacement. Therefore I (7-t- 70 0,2 = (M…
