1.	Two blocks of masses 10 kg and 4 kg are connected by a spring of negligible mass and placed on a frictionless horizontal surface. An impulse gives a velocity of 14 m's to the heavier block in the direction of the lighter block. The velocity of the center of mass is
Answer» 30 m/s 20 m/s 10 m/s 5 m/s Solution :According to law of conservation of LINCAR MOMENTUM `MV=(M+M)V_(CM)` `:.V_(CM)=(MV)/((M+M))=(10xx14)/(10+4)=10 MS^(-1)`
