15. Rotational Equilibrium
Center of Mass & Simple Balance
1PRACTICE PROBLEM
A 500 g hollow sphere is attached to a uniform metallic stick of mass 1 kg and length 1 m. The sphere can slide freely along the stick. Initially, the stick lies along the x-axis. Suppose you set the sphere at distance x from the right-hand end of the stick. Find x if the position of the center of mass of the composite system is 36 cm from the right-hand end of the stick.
