1. The problem statement, all variables and given/known data A fairgorund target consists of a uniform circular disk of mass M and radius a that can turn freely about its diamerter which is fixed in a vertical position. Iniitally the target is at rest . A bullet of mass m is moving with speed u along a horizontal line at right angles to the target . The bullet embeds itself in the target at a point distance from the rotation axis . Find the final angular speed of the target.(the moment of inertica of the disk about its roation axis is Ma^2/4 2. Relevant equations Equations for rotational energy 3. The attempt at a solution T_trans., initial + T_rot., initial, + V_initial=T_rot, final . There is no translational energy now that the bullet is embedded into the block. 1/2*m*u^2++0+0=1/2(Ma^2/4 m*b^2/4)*omega^2? Is my equation correct? There is no potential energy.
