A toy consists of a uniform solid sphere of mass 200 g attached to the end of a uniform thin rod of mass 300 g , as shown in (Figure 1). Together, the two objects are held upright on top of an axle. The toy topples over and falls, with the rod ultimately laying horizontally on a table.
What was the angular speed of the toy just before it hit the table?

Block 1 has a mass of
m1 = 450 g and Block 2 has a mass of m2 = 500 g. The pulley, which
is mounted on a horizontal axle with negligible friction through
its center, has a radius of 5.00 cm. When released from rest, Block
2 accelerates downward at a rate of 0.425 m/s2 without the cord
slipping on the pulley. What is the rotational inertia of the
pulley?
