A) \[0.15\,\,m\]
B) \[0.23\,\,m\]
C) \[1.6\,\,m\]
D) \[0.4\,\,m\]
Correct Answer: A
Solution :
By the law of conservation of .energy. Kinetic energy of mass = energy stored in spring \[\frac{1}{2}m{{v}^{2}}=\frac{1}{2}k{{x}^{2}}\] The maximum compression of the spring \[x=\sqrt{\frac{m{{v}^{2}}}{k}}\] \[x=\sqrt{\frac{0.5\times 1.5\times 1.5}{50}}=0.15\,\,m\]
