A) 0.01 m
B) 0.02 m
C) 0.05 m
D) 0.03 m
Correct Answer: C
Solution :
As the block A moves with velocity \[0.15\text{ }m{{s}^{-1}}\], 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, \[0.15\text{ }m{{s}^{-1}}\]. 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 \[\xrightarrow{0.15\,\,m{{s}^{-1}}}\]You need to login to perform this action.
