Physics

A thin rod (mass 8.28 kg, length 8.04 m) is sitting on ahorizontal, frictionless table. There is a 0.626 kg frog sitting onthe very end of the rod; you can treat the frog as a pointparticle. Suddenly the frog jumps off at speed 4.75 m/s, movinghorizontally and perpendicular to the rod. Find ω, the angularspeed of the rod after the frog jumps off, in rad/s.
