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-1 to the heavier block in the direction of the lighter block. The velocity of the centre of mass in m s-1 is 2n, then n=

Solution

vCM=m1v1+m2v2m1+m2

10×14+4×010+4=10×1414=10 m s-1 =2nn=5
