Question
Two masses each 2.2 kg are connected to each end of a massless rod of
length 1.00 m. A light string attached to the center of the rod holds the
rod and masses in equilibrium horizontally. A wad of clay (mass 123 g)
is thrown vertically upward with a speed v = 2.7 m/s towards the mass on
the right. The clay collides with the mass and sticks to it. The system is
free to rotate in a vertical plane (ignore friction)
