 Two rectangular blocks A and B of masses 2 kg and 3 kg respectively are connected by a spring of spring constant 10.8 Nm-1 and are placed on a frictionless horizontal surface. The block A was given an ‘initial velocity of 0.15 ms-1 in the direction shown in the figure. The maximum compression of the spring during the motion is​
  • a)
    0.01 m
  • b)
    0.02 m
  • c)
    0.05 m
  • d)
    0.03 m
Correct answer is option 'C'. Can you explain this answer?

As the block A moves  with velocity 0.15ms−1, it compresses the  spring which pushes B towards right. A goes on compressing the spring till the velocity acquired by B becomes equal to the velocity of A, ie, 0.15ms−1,
Let this velocity be v. Now, spring is in a state of maximum compression. Let x be the maximum compression at this stage. 
According to the law of conservation of linear momentum, we get  mAu = (mA+mB)v or v = 
According to the law of conservation of energy,
