Two blocks B and C of masses 1 kg and 2 kg respec- tively are connected by a massless elastic spring of spring constant 150 Nm and placed on a horizontal frictionless surface as shown in Fig. 7.6. A third block A of mass 1 kg moves with a velocity of 3 ms' along the line joining B and C and collides with B. If the collision is perfectly elastic and the natural length of the spring is 80 cm, find the minimum separation between blocks B and C. -1 C
