Physics for the IB Diploma

Two masses of 2.0 kg and 4.0 kg are held with a compressed spring between them. If the masses are released, the spring will push them away from each other. If the smaller mass moves off with a speed of 6.0 m s $^{-1}$ , what is the speed of the other mass? (See Figure 6.11.)
