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 \[\frac{1}{2}m{{v}^{2}}=\frac{1}{2}k{{x}^{2}}\] \[{{x}^{2}}=\frac{m{{v}^{2}}}{k}\] The maximum compression of the spring \[x=\sqrt{\frac{m{{v}^{2}}}{k}}\] \[x=\sqrt{\frac{0.5\times 1.5\times 1.5}{50}}=0.15\,m\]You need to login to perform this action.
