A) \[2\,cm\]
B) \[5\,cm\]
C) \[10\,cm\]
D) \[20\,cm\]
Correct Answer: C
Solution :
At the time of maximum compression velocities of both the blocks will be same (say V) By conservation of linear momentum. \[2\times 1=4V\] \[V=0.5m/s\] By conservation of energy. \[\frac{1}{2}\times 2\times {{(1)}^{2}}=\frac{1}{2}\times 4\times {{(0.5)}^{2}}+\frac{1}{2}\times 100\times {{(X)}^{2}}\] \[X=0.1m=10cm\]You need to login to perform this action.
