Block A and B have masses 40 kg. and 60 kg resp. They are placed on a smooth surface and the spring connected between them is stretched by 1.5m. If they are released from rest, determine the speeds of the blocks at the instant the spring became unstrentched(A) V1 = 3 m/s, V2 = 4.5 m/s (B) V1 = 4.5 m/s, V2 = 3 m/s(C) V1 = 5 m/s, V2 = 6 m/s (D) V1 = 4 m/s, V2 = 3 m/s
