1. The problem statement, all variables and given/known data A mass m1 with speed v1i colides with a mass m2 of length 1m, initially at rest, and gets stuck with it. (a) Express the angular velocity in functon of v1i. (m=m1=m2) 2. Relevant equations w=v/r 3. The attempt at a solution Since the collision is totally inelastic I can say m1*vi1=(m1+m2)vf ⇔ Since all masses are equal I can say vi1=2vf⇔vf=v1i/2 Since w=v/r w=vf/r⇔w=0.5*v1i/0.5⇔w=v1i This is wrong for some reason... Can anyone lead me in the correct way? Thanks. D.
