1. The problem statement, all variables and given/known data Ok... "A small bob of putty of mass m falls from the ceiling and lands on the outer rim of a turntable of radius R and moment of inertia I_0 that is rotating freely with angular speed of w_i, about its vertical fixed symmetry axis..." "After several turns the blob flies off the edge of the turntable. What is the angular speed of the turntable after the blob flies off." 2. Relevant equations 3. The attempt at a solution Ok.. so angular momentum is conserved... so when the blob hits the turn table .. I_0*w_i=(I_0+m*R^2)w_f Solve for w_f... but when the blob flies off, do they does the final angular velocities of the turntable and putty different or similar? Does the putty fly off with a velocity of w_f or something else... does this look logical? Angular Momentum Initial= Angular Momentum Final.... But what next?
