Do not store equations in your calculator. You have to solveproblems on your own; memorizing final algebraic expressions from homework assignments and just plugging numbers into them will not give you full credit. Leave all your work. ________________________________________________________________________________ In the figure below right, a small 2.00 kg block slides down a frictionless surface through height h= 1.00 m and then sticks to a uniform vertical rod of mass M= 3.00 kg and length L= 1.50 m. The rod and block rotate together around point O. The uniform rod has rotational inertia I = (1/3)ML2about point O. a) What is the angular velocity of the rod-block system just after the block hits the rod? Since the surface is frictionless, the mechanical energy of the block is conserved while it is sliding down the surface. The velocity of the block just before hitting the rod is
