If Fext = 0, no change in COM,
Linear momentum would be conserve then, i.e.
m1(dx1/dt) = m2(dx2.dt)
Linear momentum would be conserve then, i.e.
m1(dx1/dt) = m2(dx2.dt)

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
